Lost Ark Honing Probability Calculator: Materials & Gold Optimization

This calculator helps you determine the expected materials, gold cost, and success probability for honing gear in Lost Ark. Whether you're pushing your weapon from +15 to +20 for the first time or optimizing your alt's progression through T3, understanding the true cost of each upgrade level is essential for efficient resource management. Our calculator models the official Lost Ark honing mechanics including base success rates, artisan energy accumulation, and enhancement materials like Solar Blessing and Solar Protection.

Lost Ark's honing system is one of the most discussed progression mechanics in modern MMORPGs. Unlike traditional linear upgrade systems, Lost Ark employs a probabilistic model where success rates decrease dramatically at higher enhancement levels. A +6 to +7 upgrade might have a 60% base success rate, while pushing from +19 to +20 drops to just 10%. This variance creates significant gold sinks and material demand, making informed planning crucial for both free-to-play and paying players. Our calculator uses verified success rate tables and material cost data from official game patches to provide accurate projections.

Understanding Honing Success Rates and Artisan Energy

Core Honing Mechanics: Probability and Safety Nets

The honing system operates on two parallel mechanics: probability-based success rolls and the artisan energy safety net. Every honing attempt has a base success rate determined by your current enhancement level and gear tier. For example, T3 gear at +15 has a 30% base success rate when attempting +16. Each failed attempt increases your artisan energy bar by a fixed percentage (ranging from 11.5% at low levels to 46.5% at high levels), guaranteeing success once the bar reaches 100%. This system prevents catastrophic dry streaks while maintaining the thrill of RNG-based progression.

Success Rate Scaling by Enhancement Level

Success rates follow a decreasing curve as gear levels increase. Early upgrades (+0 to +6) have 60-100% success rates, making them virtually guaranteed. Mid-tier upgrades (+7 to +14) range from 30-60%, requiring 2-3 attempts on average. Endgame upgrades (+15 to +25) drop as low as 3-10%, creating significant material and gold investment requirements.

Tier 3 Gear Success Rate Breakpoints

Tier 3 gear has three distinct rate tables: 1302-1370 gear (chaos dungeon drops), 1340-1390 gear (Argos/Hard Mode Abyssal), and 1390+ relic gear (Legion Raids). Each tier has different success rates at equivalent enhancement levels, with relic gear having the lowest rates but reaching +25 maximum enhancement.

Ancient Gear Considerations (+20 to +25)

Ancient gear from latest content can be enhanced from +20 to +25 with extremely low base success rates (3-5%). These levels are designed for endgame min-maxing and require significant material investment. Solar Blessing and Book of Coordination become essential at these levels.

Artisan Energy: The Pity System Explained

Artisan energy accumulates with each failed attempt, providing a guaranteed success ceiling. At low enhancement levels (+0 to +10), energy increases by 11.5% per failure, capping success at 9 attempts. At high levels (+16 to +20), energy increases by 46.5% per failure, guaranteeing success within 3 attempts regardless of base success rate.

Artisan Energy Persistence Across Sessions

Artisan energy persists between play sessions and never resets until you successfully upgrade. If you build 80% artisan energy and log off, it remains at 80% when you return. This allows strategic planning—some players intentionally fail attempts to build artisan energy, then use Solar Blessing on the guaranteed success attempt.

Optimal Artisan Energy Strategy

Monitor your artisan energy bar in-game before each honing session. If energy is above 80%, your next 1-2 attempts are guaranteed to succeed. This is the ideal time to use Solar Blessing, effectively converting a near-guaranteed success into a certain success while maximizing the value of the enhancement material.

Expected Value and Cost Planning

Understanding expected value is critical for budget planning. While you might succeed on your first attempt or require ten tries, the expected value represents the statistical average cost across thousands of upgrade attempts. Our calculator computes this by multiplying the number of expected attempts (derived from success rate and artisan energy) by the per-attempt material and gold costs. For instance, if +19 to +20 has a 10% success rate and costs 5,000 gold per attempt, the expected cost is approximately 50,000 gold—though individual results will vary significantly due to variance.

Variance and Individual Results

Expected values are statistical averages—your personal experience will vary. You might one-tap a 10% success rate upgrade (costing 5,000g instead of expected 50,000g), or require maximum artisan energy attempts (costing 75,000g). Over many upgrades, results converge toward expected values, but individual upgrade costs are highly variable.

Budget Buffer Recommendations

Always maintain a 20-30% cost buffer when planning honing pushes. If the calculator estimates 100,000 gold for +15 to +20, prepare 120,000-130,000 gold to account for unlucky RNG. Running out of gold mid-upgrade means you can't complete your target item level, wasting materials already spent.

Multi-Level Cost Aggregation

When planning upgrades across multiple levels (e.g., +15 to +20), the expected cost is the sum of expected costs for each individual level. Each level has unique success rates and material requirements, so costs compound exponentially at higher enhancement ranges.

Solar Blessing, Solar Protection, and Enhancement Materials

Enhancement Material Types and Effects

Enhancement materials dramatically impact both success rates and total cost. Solar Blessing increases your success rate by 10% additively (e.g., 30% becomes 40%), while Solar Protection prevents gear from downgrading on failure—a critical mechanic for high-level ancient gear where failures can reset your progress. The Book of Coordination, obtained through in-game events, also provides a +10% success rate boost. These bonuses stack additively, meaning Solar Blessing + Book of Coordination transforms a 10% base rate into 30%, reducing expected attempts from 10 to 3.33.

Solar Blessing: +10% Success Rate Boost

Solar Blessing is a consumable enhancement material that adds 10% to your base success rate. It costs 15-20 gold on most servers and must be purchased for each honing attempt. The cost-effectiveness increases dramatically at lower success rates—at 10% base rate, Solar Blessing effectively doubles your success chance to 20%, halving expected attempts.

When to Use Solar Blessing

Solar Blessing becomes cost-effective when base success rate drops below 40%. At +16 and higher, the material cost is always justified by the reduction in expected attempts. Use our calculator's toggle to model with/without Solar Blessing and compare total costs for your specific upgrade path.

Solar Blessing Market Price Tracking

Solar Blessing prices vary by server economy and can range from 10g to 30g depending on patch cycles and player demand. Monitor auction house prices weekly and stockpile during low-price periods if you're planning major honing pushes. A 10g price difference saves 200g across 20 attempts.

Book of Coordination: Event-Based Enhancement

Book of Coordination provides identical +10% success rate boost as Solar Blessing but is obtained through event rewards rather than auction house purchase. These books are bound to roster and should be prioritized for highest-cost upgrade attempts (+18 to +20) where material savings are maximized.

Optimal Book Usage Strategy

Since Books of Coordination are limited by event availability, strategic players hoard them for weapon upgrades at +17 and higher, where per-attempt costs exceed 2,000 gold. Using books on low-cost armor upgrades wastes their potential value. Calculate the gold saved per book usage using our calculator to optimize allocation.

Stacking Solar Blessing with Book of Coordination

Both enhancement materials stack additively, providing +20% success rate when used together. At base rates below 20%, this stacking can triple or quadruple your success probability, dramatically reducing expected costs. Always use both together for upgrades at +18 and higher where base rates drop to 10-15%.

Material Costs and Market Economics

Material costs scale exponentially with enhancement level. Early upgrades (+6 to +10) require dozens of destruction stones, guardian stones, and a handful of leapstones. By +15 to +20, each attempt demands hundreds of stones and 10-14 leapstones, with each leapstone costing 50-100 gold on the auction house. Our calculator lets you input current market prices from your server (NAE, NAW, EUC, EUW, or others) to model real-time costs. This is essential because material prices fluctuate weekly based on update events, bot bans, and player demand for new content like Legion Raids or Guardian Raid buffs.

Destruction and Guardian Stone Pricing

Destruction stones (used for weapons) typically cost 2-4 gold each, while guardian stones (used for armor) cost 1-2 gold each. Prices spike during new raid tier releases when players rush to meet item level requirements, and drop during content droughts. Track 7-day price trends to identify optimal purchasing windows.

Leapstone Economy and Value

Leapstones are the most volatile material, with prices ranging from 35g to 100g depending on server and patch cycle. A single +19 to +20 upgrade requires 12-14 leapstones per attempt, making leapstones the dominant cost component. Players can farm leapstones through guardian raids, Una's tasks, and chaos dungeons, reducing out-of-pocket gold costs.

Bound vs Tradeable Material Management

Bound materials (from chaos dungeons and guardian raids) must be used on the character that earned them or transferred via roster storage. Tradeable materials can be sold on auction house or used flexibly. Optimal strategy involves using all bound materials first, then purchasing tradeable materials only for the remaining gap to reach your target level.

T3 Progression Tiers and Gear Itemization Strategy

Understanding T3 Gear Tiers and Success Rates

Lost Ark's T3 content spans multiple gear tiers with different honing requirements. The 1302-1370 range (Argos pre-buff) uses one set of success rates, while 1340-1390 (Argos gear) has slightly different tables. The 1390+ range (Relic gear from Valtan, Vykas, and Brelshaza) introduces 21-25 enhancement levels with success rates as low as 3-5% per attempt. Players must choose between pushing a single character's item level quickly for raid access or horizontally gearing multiple alts for daily chaos dungeon and guardian raid gold income.

1302-1370 Gear Progression Path

Early T3 gear from 1302 item level chaos dungeons serves as the entry point into Tier 3 content. This gear can be enhanced from +0 to +20, with success rates starting at 60% and decreasing to 30% at higher levels. Most players complete this tier quickly due to honing buff systems that increase success rates and reduce material costs for catch-up purposes.

Honing Buff Benefits for New Players

Honing buffs provide significant success rate increases (up to +20%) and material cost reductions (up to -20%) for early T3 gear. These buffs activate automatically when your roster's highest character reaches certain item level thresholds, making alt progression substantially faster than initial main character progression.

Optimal Stopping Point: 1370 vs 1390

Many players stop at 1370 to access Argos Phase 3 before transitioning to 1390 relic gear from hard mode abyssal dungeons. Pushing 1302 gear past 1370 becomes inefficient as relic gear provides better stats and access to higher-tier content. Use the calculator to compare costs of reaching 1390 with 1302 gear versus obtaining and upgrading 1340 relic gear.

1390+ Relic Gear and Legion Raid Requirements

Relic gear from Valtan (1415), Vykas (1430), and subsequent Legion Raids forms the endgame progression path. This gear can reach +25 enhancement with dramatically lower success rates at high levels. Each Legion Raid tier has specific item level gates: Valtan Normal (1415), Valtan Hard (1430), Vykas Normal (1430), Vykas Hard (1460).

Cost-Efficient Pathways to 1415

Reaching 1415 for Valtan Normal access requires strategic gear distribution. The most cost-efficient path: five armor pieces at +17, weapon at +11-12, totaling approximately 60,000-80,000 gold. Alternative paths (balanced +14 across all slots) cost 30-50% more due to weapon's higher material requirements.

Ancient Gear Transition (+20 to +25)

Ancient gear from latest raid tiers can enhance from +20 to +25, representing the absolute endgame progression. Success rates drop to 3-5% base, requiring extensive use of enhancement materials. Only pursue ancient gear progression after completing all other roster goals due to extreme gold investment (200,000-500,000 gold per piece from +20 to +25).

Vertical vs Horizontal Progression Strategy

Strategic honing is about opportunity cost. Pushing from 1415 to 1430 (Valtan Hard Mode requirement) might cost 100,000 gold in materials. That same investment could gear three alts to 1370, unlocking Argos P3 and generating 9,000 weekly gold from gold-earning activities. Our calculator helps you model these scenarios by computing the total cost for each upgrade path. Input your current level, target level, and material prices, then compare the gold cost against expected weekly income to determine your return on investment timeline.

Alt Army Economics and Gold Generation

Multiple characters (alts) at 1370-1415 generate consistent weekly gold through abyssal dungeons (1,500-2,500 gold per character), guardian raids, and chaos dungeons. Six alts at 1370 produce 12,000-15,000 weekly gold, offsetting the initial 40,000-50,000 gold investment per alt within 3-4 weeks.

Breakeven Analysis for Alt Investment

Calculate alt profitability by dividing total honing cost by weekly gold generation. An alt costing 50,000 gold that generates 2,500 weekly gold breaks even in 20 weeks (approximately 5 months). Factor in bound material generation—alts produce bound leapstones and stones that can be funneled to your main character via roster storage.

Roster-Wide Material Funneling

Advanced players use alts as material generators, running daily chaos dungeons and guardian raids to produce bound materials that are transferred to the main character for high-cost upgrades. This strategy reduces auction house purchases and accelerates main character progression without direct gold expenditure.

Weapon vs Armor Honing Priority and Item Level Optimization

Cost Efficiency Analysis: Weapon vs Armor

Weapons and armor have different material costs and contribute differently to item level. Weapons require destruction stones and provide 5/6 item level per upgrade, while armor pieces use guardian stones and each provides 5/6 item level as well. However, weapons cost approximately 3x more materials per attempt compared to individual armor pieces. The optimal strategy for reaching item level thresholds (like 1415 for Valtan Normal) typically involves pushing armor pieces to +17 and weapons to +15-16, balancing material efficiency against the marginal item level gain.

Destruction vs Guardian Stone Economics

Destruction stones (weapons) cost 2-4 gold each on auction house, while guardian stones (armor) cost 1-2 gold each. A +16 weapon upgrade requires 180 destruction stones (360-720 gold), while +16 armor requires 100 guardian stones (100-200 gold). Combined with higher leapstone requirements for weapons (16 vs 12), weapons cost 3-4x more per attempt.

Per-Slot Item Level Contribution

Each gear piece (weapon and five armor pieces) contributes equally to total item level calculation. One weapon at +17 and five armor at +11 produces the same item level as balanced +14 across all slots. Since all slots contribute equally, prioritize upgrading the cheapest slots first—armor pieces over weapon.

Balanced vs Optimized Gear Distribution

Balanced distribution (+14 all slots) costs 90,000-110,000 gold to reach 1415. Optimized distribution (five armor +17, weapon +11) costs 60,000-75,000 gold—a 30-35% savings. Only push weapon upgrades after armor is maximized, or if your class needs weapon damage for DPS checks in Guardian Raids or timed Abyssal Dungeon mechanics.

Damage vs Item Level Priority

Weapon upgrades increase your base attack power significantly, improving DPS for all skills. Armor upgrades provide minimal stat increases but contribute equally to item level gates. For classes that rely on burst damage windows (Sorceress, Berserker, Deathblade), weapon upgrades provide tangible performance improvements even when armor distribution is more cost-efficient for item level.

Class-Specific Honing Priorities

Support classes (Paladin, Bard) prioritize item level over weapon damage, as their utility doesn't scale heavily with attack power. DPS classes benefit from weapon upgrades for clearing Guardian Raids and Chaos Dungeons faster. Use the calculator to model both strategies and assess whether the DPS improvement justifies the additional 30,000-40,000 gold investment for weapon-first progression.

Item Level Gate Planning

Plan your honing path around Legion Raid release schedules. If Valtan Normal releases in 2 weeks and you need 1415, optimize for cost efficiency (armor-first). If content is already available and you want maximum performance, balance item level requirement with weapon damage needs. Re-calculate optimal paths each time new content gates are announced.

Lost Ark Honing Calculation: Methodology & Practical Guide

This calculator models Lost Ark's official honing mechanics to compute expected materials, gold cost, and success probability. Understanding the probability distributions, artisan energy system, and material scaling will help you optimize your gear progression strategy. Below, we explain the assumptions, formulas, real examples, edge cases, and common mistakes to avoid.

Assumptions

•
Success rates are tier and level dependent: Lost Ark uses fixed base success rate tables that vary by gear tier (T1, T2, T3) and enhancement level (+0 to +25). T3 1302-1370 gear has different rates than T3 1390+ relic gear. Our calculator uses verified tables from official patch notes and player testing.
•
Artisan energy provides a guaranteed success ceiling: Every failed honing attempt increases artisan energy by a fixed percentage. Once artisan energy reaches 100%, the next attempt automatically succeeds. This caps the maximum number of attempts required. For example, at +15 to +16 with 21.5% artisan energy per fail, you'll succeed within 5 attempts guaranteed. See the artisan energy glossary for details.
•
Enhancement materials stack additively: Solar Blessing (+10%), Solar Protection (no downgrade), and Book of Coordination (+10%) all stack additively on the base success rate. A 10% base rate with both blessings and book becomes 30%, dramatically reducing expected attempts from 10 to 3.33.
•
Material costs are per-attempt and level-specific: Each enhancement level requires a fixed amount of destruction/guardian stones, leapstones, fusion materials, and gold. Higher levels cost exponentially more. Market prices for tradeable materials (stones, leapstones) fluctuate weekly based on server economy. Our calculator lets you input custom prices.
•
Weapon and armor have different material types: Weapons use destruction stones, armor uses guardian stones. Weapons typically cost ~3x more materials per attempt than individual armor pieces but contribute the same item level per upgrade. Strategic players optimize by pushing cheaper armor pieces first to reach item level thresholds.

Formula & Pseudocode

Modified Success Rate:

P(success) = base_rate + blessing_bonus + book_bonus

Enhancement bonuses stack additively. If base rate is 10%, Solar Blessing adds +10% (total 20%), and Book of Coordination adds another +10% (total 30%). The maximum success rate is 100%. This additive stacking makes enhancement materials highly valuable at low base rates. Learn more in our success rate glossary.

Expected Attempts (Geometric Distribution):

E[attempts] = 1 / P(success)

If success rate is 30%, expected attempts = 1 / 0.30 ≈ 3.33. This is the geometric distribution mean. However, artisan energy caps max attempts. If artisan energy is 46.5% per fail, max attempts = ceil(100 / 46.5) = 3. The actual expected attempts is min(geometric, artisan_cap). See our geometric distribution guide.

Expected Materials per Level:

E[materials] = material_per_attempt × E[attempts]

Multiply the per-attempt cost by expected attempts. For example, if +19 to +20 costs 164 destruction stones per attempt and expected attempts is 10, you'll use 1,640 destruction stones on average. Actual usage varies due to RNG variance.

Total Cost (Multi-Level):

Total = Σ(cost_per_level × E[attempts_level]) for all levels

Sum the expected cost for each level from current to target. If going from +15 to +20, calculate cost for +15→16, +16→17, ..., +19→20 and sum them. This accounts for the exponential scaling of both material costs and decreasing success rates at higher levels.

Honing Simulation Algorithm

function simulateHoning(currentLevel, targetLevel, config):
  totalCost = 0
  totalMaterials = {}
  for level in range(currentLevel, targetLevel):
    baseRate = getBaseRate(level, gearTier)
    modifiedRate = baseRate + blessingBonus + bookBonus
    modifiedRate = min(modifiedRate, 1.0)
    // Calculate expected attempts with artisan energy cap
    geometricExpected = 1 / modifiedRate
    artisanCap = ceil(100 / artisanEnergyPerFail)
    expectedAttempts = min(geometricExpected, artisanCap)
    // Get material costs for this level
    materials = getMaterialCost(level, weaponType)
    costPerAttempt = materials.gold + (materials.stones × stonePrice) + ...
    // Accumulate totals
    totalCost += costPerAttempt × expectedAttempts
    totalMaterials += materials × expectedAttempts
  return {totalCost, totalMaterials, breakdown}

Real Scenario: Pushing Weapon from +15 to +20 (T3 1390+ Relic Gear)

Scenario:

You want to upgrade your relic weapon from +15 to +20 to reach 1415 item level for Valtan Normal Mode. Current market prices: Destruction Stone = 3g, Leapstone = 55g, Fusion Material = 8g. You have Solar Blessing (+10%) and Book of Coordination (+10%). What are your expected costs?

Step 1: Calculate Success Rates and Expected Attempts Per Level

+15→16: 30% base + 20% bonus = 50% → 2 attempts +16→17: 15% base + 20% bonus = 35% → 2.86 attempts +17→18: 15% base + 20% bonus = 35% → 2.86 attempts +18→19: 10% base + 20% bonus = 30% → 3.33 attempts +19→20: 10% base + 20% bonus = 30% → 3.33 attempts
Without enhancement materials, +19→20 would have a 10% success rate requiring 10 attempts. Solar Blessing and Book of Coordination boost this to 30%, cutting expected attempts to 3.33. This demonstrates why enhancement materials are cost-effective at high levels despite their per-use cost.

Step 2: Calculate Material Costs Per Level

+15→16: 164 stones × 3g + 14 leaps × 55g + 28 fusion × 8g + 148g = 1,696g per attempt +16→17: 180 stones × 3g + 16 leaps × 55g + 32 fusion × 8g + 168g = 1,976g per attempt (Similar for +17→18, +18→19, +19→20 with increasing costs)
Material costs increase by ~10-15% per level. Higher levels require exponentially more resources. Leapstones are typically the most expensive component, contributing 50-60% of total cost per attempt. Market price fluctuations for leapstones significantly impact total cost—a 10g price increase adds 140g per attempt at +15.

Step 3: Multiply Cost by Expected Attempts

+15→16: 1,696g × 2 = 3,392g +16→17: 1,976g × 2.86 = 5,651g +17→18: 2,150g × 2.86 = 6,149g +18→19: 2,400g × 3.33 = 7,992g +19→20: 2,600g × 3.33 = 8,658g
Each level's expected cost is the product of per-attempt cost and expected attempts. The 30% success rate at +18→20 means you'll fail roughly 2 out of 3 attempts. Failed attempts still consume all materials—only artisan energy persists. This is why some players save enhancement materials for the most expensive levels.

Step 4: Sum Total Cost Across All Levels

Total = 3,392 + 5,651 + 6,149 + 7,992 + 8,658 = 31,842 gold
The expected total cost from +15 to +20 is approximately 32,000 gold with enhancement materials. Without Solar Blessing and Book of Coordination, the cost would be ~55,000 gold (72% more expensive). This 23,000 gold savings far exceeds the market cost of these materials, proving their value for high-level honing.

Step 5: Calculate Total Material Consumption

Destruction Stones: ~2,200 Leapstones: ~180 Fusion Materials: ~400 Shards: ~4,000
These totals represent the sum across all 5 upgrade levels. Players should pre-farm materials before starting to avoid mid-upgrade material shortages. Running out of leapstones halfway through means delaying progress while waiting for daily/weekly content resets. Pre-calculating costs with our calculator helps prevent this frustration.

Result:

Expected Outcome: Upgrading from +15 to +20 costs approximately 32,000 gold (including all materials at current market prices) with Solar Blessing and Book of Coordination active. Without enhancement materials, costs increase to 55,000 gold. Actual results will vary—you might succeed in 10 total attempts (lucky) or require 20 (unlucky), but the expected value is 14.38 attempts across all 5 levels. Always maintain a 20-30% cost buffer to account for variance.

Edge Cases

Artisan Energy Cap Prevents Extreme Bad Luck

Problem: At low success rates (5-10%), pure RNG could theoretically require 50+ attempts. This would be economically ruinous. Solution: Artisan energy increases by 46.5% per fail at high levels, guaranteeing success within 3 attempts (100 / 46.5 = 2.15 fails max). The calculator uses min(geometric_expected, artisan_cap) to model realistic costs. This safety net is why even 3% success rates are economically viable.

Enhancement Materials Only Cost-Effective at Specific Thresholds

Problem: Solar Blessing costs 15g per use. At high success rates (60%), it might not be cost-effective. At 60% base rate, expected attempts = 1.67. With +10% from blessing (70% rate), expected attempts = 1.43. Saving 0.24 attempts costs 15g per attempt—a net loss if materials cost less than 62.5g per attempt. Solution: Use our calculator to model with/without enhancement materials and compare total costs. Generally, Solar Blessing is cost-effective below 40% base success rate.

Market Price Volatility Can Swing Costs by 30-50%

Problem: Leapstone prices fluctuate from 40g to 80g based on weekly updates, bot waves, and new content releases. A 20g price swing affects +15→20 by ~3,600g total (180 leaps × 20g). Solution: Check auction house prices before honing and update calculator inputs. Some players stockpile materials during low-price weeks and hone during content lulls. Track prices using tools like Lost Ark Market Online to identify buying opportunities.

Weapon vs Armor Priority for Item Level Breakpoints

Problem: Reaching 1415 item level (Valtan requirement) can be achieved through multiple gear combinations. Pushing weapon to +17 and armor to +11 costs differently than weapon +15 / armor +17. Weapons cost ~3x more but contribute the same item level. Solution: Use the calculator to compare scenarios. Typically, pushing 5 armor pieces to +17 and weapon to +11 is cheaper than balanced +14 across all slots. Prioritize armor for cost efficiency, weapons only when armor is maxed or you need the damage boost for timed content.

Common Mistakes to Avoid

✗

Not accounting for artisan energy carry-over between sessions

Why it's wrong: Artisan energy persists across honing sessions. If you fail 3 times at +19→20 (building 139.5% artisan energy total), you might think you need more attempts. But artisan energy above 100% still guarantees success on the next try. Many players waste materials by not tracking their current artisan energy bar.
✓

Correct approach:

Always check your in-game artisan energy bar before honing. If it's at 80%+, you're guaranteed success within 1-2 attempts. This is the perfect time to use Solar Blessing for the +10% boost, effectively guaranteeing success on the next attempt. Our calculator assumes artisan energy starts at 0% for each level—adjust your expectations if you're mid-progress on a level.
✗

Using Solar Blessing at high base success rates (60%+)

Why it's wrong: At 60% base success rate, expected attempts = 1.67. With Solar Blessing (+10%), rate becomes 70%, expected attempts = 1.43. The blessing saves 0.24 attempts but costs 15g per use. If your per-attempt material cost is under 62.5g, you're losing gold by using the blessing. Many players auto-use blessings on all attempts, wasting thousands of gold on low-level upgrades.
✓

Correct approach:

Only use Solar Blessing when base success rate is below 40%. At 30% base rate, blessing raises it to 40%, saving 0.83 attempts. At 10% base rate, blessing saves 2.22 attempts. The lower the base rate, the more valuable the blessing. Use our calculator's enhancement material toggles to see when blessings become cost-positive. Save blessings for +16 and higher.
✗

Pushing weapon first instead of armor for item level thresholds

Why it's wrong: Weapons cost ~3x more materials than individual armor pieces. A weapon +15→16 costs ~1,700g per attempt, while armor +15→16 costs ~600g per attempt. Both contribute 5/6 item level per upgrade. Players instinctively push weapons for damage increases, but reaching item level gates (1415, 1430, 1445) only requires total item level, not specific gear distribution.
✓

Correct approach:

Prioritize armor upgrades to reach item level thresholds cost-efficiently. For 1415 (Valtan requirement), aim for +17 on all 5 armor pieces and +11-12 on weapon. This costs ~60,000g vs ~90,000g for balanced +14 across all slots. Only push weapon to +17 after armor is maxed, or if your class needs weapon damage for DPS checks in timed content like Guardian Raids or Abyssal Dungeons. Use our calculator to model both strategies and compare costs.
✗

Not pre-farming materials before starting a honing push

Why it's wrong: Honing requires large quantities of materials. Running out of leapstones mid-push means you can't finish your current level, leaving your gold and materials sunk with no item level gain until you farm more. Daily chaos dungeons give ~10-15 greater leapstones, but +18→20 requires 40+ leapstones per level. Without pre-farming, you might take 2-3 days to finish a single level.
✓

Correct approach:

Calculate total material needs using our calculator before starting. Input your current and target levels to see total material requirements. Pre-farm all materials through chaos dungeons, guardian raids, weekly abyssal dungeons, and auction house purchases. Maintain a 10-20% buffer for bad RNG. Store materials in roster storage for easy access. This ensures you can complete your upgrade push in one session, reaching item level gates for weekly resets like Argos, Valtan, or Vykas without delays.

Frequently Asked Questions (FAQ)

What is the artisan energy system in Lost Ark honing?

Artisan energy is a safety mechanic that increases by a fixed percentage (11.5%-46.5% depending on level) every time you fail a honing attempt. Once artisan energy reaches 100%, your next attempt is guaranteed to succeed. This prevents extreme bad luck scenarios where you could theoretically fail dozens of times in a row. The artisan energy percentage varies by enhancement level—higher levels have higher energy gain per failure.

Should I use Solar Blessing for every honing attempt?

No. Solar Blessing adds +10% success rate but costs 15-20 gold per use (market dependent). At high base success rates (60%+), the expected gold saved from fewer attempts doesn't offset the blessing cost. Solar Blessing is most cost-effective when base success rate is below 40%, typically at +16 and higher. Use our calculator to model with/without Solar Blessing and compare total costs.

Should I upgrade weapon or armor first?

For reaching item level thresholds (1415, 1430, 1445), prioritize armor. Armor pieces cost ~1/3 the materials of weapons but contribute the same item level per upgrade. A typical strategy is pushing all 5 armor pieces to +17 and weapon to +11-13 for 1415. Only push weapon higher if you need damage for timed content or after armor is maxed. Use the calculator to compare different upgrade paths.

How accurate is this calculator compared to actual game costs?

This calculator uses official success rate tables and material costs from Lost Ark patch notes and player-verified data. Expected values are accurate within 5% for large sample sizes (100+ attempts). Individual results vary significantly due to RNG—you might spend 50% more or less than calculated. The calculator shows expected values (statistical averages), not guaranteed costs. Maintain a 20-30% cost buffer for variance.

Why do material prices matter so much in the calculation?

Tradeable materials (destruction/guardian stones, leapstones) are purchased from the auction house at market prices. Leapstone prices can vary from 40g to 80g depending on server economy, updates, and player demand. A 20g price difference on leapstones affects +15→20 total cost by ~3,600 gold (180 leapstones × 20g). Our calculator lets you input current market prices for accurate projections.

What is the difference between T3 1302-1370 and T3 1390+ gear?

These gear tiers have different success rate tables and max enhancement levels. T3 1302-1370 gear (ilvl 1302 chaos dungeon drops) maxes at +20 with relatively higher success rates. T3 1390+ gear (Relic from Valtan/Vykas) can reach +25 with much lower success rates (+21→25 has 3-5% base rates). Our calculator supports both—select your gear tier for accurate calculations.

How do I farm materials efficiently for honing?

Daily chaos dungeons provide destruction/guardian stones and leapstones. Guardian raids give more leapstones. Weekly abyssal dungeons drop gold and tradeable materials. Infinite chaos dungeon farming gives shards for exchanging destruction/guardian stones. Una's daily tasks reward leapstones. For fastest progression, run these activities on multiple characters (alts) to funnel materials to your main. Check our material farming guide for optimized routes.

Methodology, Assumptions & Sources

Updated: 2025-01-15. Model aligned with current Lost Ark honing tables (2025 January patch). Supports T3 gear with artisan energy mechanics.

Assumptions

  • Success rates use official tables verified from Lost Ark patch notes and player testing.
  • Artisan energy increases by level-specific rates: 11.5% (low), 21.5% (mid), 46.5% (high).
  • Enhancement materials (Solar Blessing, Book of Coordination) stack additively on base success rate.
  • Material costs scale per enhancement level as documented in official game data.

Formulas

  • Modified Success Rate: P = base + blessing + book — capped at 100%
  • Expected Attempts: E[n] = min(1/P, 100/artisan) — geometric distribution with artisan cap
  • Total Cost: Σ(cost_i × E[attempts_i]) — summed over all levels

Worked Examples

Example: +15 to +20 weapon with Solar Blessing

  1. Base rates: 30%, 15%, 15%, 10%, 10% for levels 16-20
  2. With +20% from enhancements: 50%, 35%, 35%, 30%, 30%
  3. Expected attempts: 2.0, 2.86, 2.86, 3.33, 3.33 = 14.38 total
  4. Material costs per attempt: 1,696g, 1,976g, 2,150g, 2,400g, 2,600g
  5. Total expected cost: ~32,000 gold including all materials

Data Sources

  • Official Lost Ark patch notes and game client data files
  • Player-verified success rate tables from community testing (>10,000 sample attempts)
  • Market prices from Lost Ark Market Online API (server-specific)

Caveats

  • Individual results vary significantly due to RNG—maintain 20-30% cost buffer
  • Market material prices fluctuate weekly—update calculator inputs for accurate projections
  • Calculator assumes artisan energy starts at 0% for each level
