Elden Ring Drop Rate Guide 2025 – Discovery Stat, Arcane Builds & Rare Weapon Farming

Discovery Formula: Logarithmic Scaling Explained

Discovery Sources & Stacking Mechanics

Discovery is calculated additively from multiple sources before applying the logarithmic formula: Base Discovery = 100 (all characters start here). Arcane scaling = +2 Discovery per Arcane point (50 Arcane = +100 Discovery). Silver Scarab talisman = +75 Discovery (best single source). Silver-Pickled Fowl Foot consumable = +50 Discovery for 3 minutes (stackable with talisman). Maximum realistic Discovery = 100 (base) + 130 (65 Arcane, soft cap) + 75 (Scarab) + 50 (Fowl Foot) = 355 Discovery. This yields 1.55× drop rate multiplier (+55% drops). Practical max for sustained farming (without consumables) = 305 Discovery = 1.484× (+48.4%).

Arcane Soft Caps: 50 vs 60 vs 80 Arcane Analysis

Arcane has no hard caps for Discovery (+2 per level up to 99), but soft caps exist for Arcane-scaling weapon damage. For pure Discovery farming: 50 Arcane = 200 Discovery total (1.30× drops, +30.1%), moderate investment (level 30-40 with optimal starting class). 60 Arcane = 220 Discovery (1.342× drops, +34.2%), high investment (level 40-50), only +4.1% more drops than 50 Arcane for 10 levels. 80 Arcane = 260 Discovery (1.415× drops, +41.5%), extreme investment (level 60-70), only +11.4% more than 50 Arcane for 30 levels. Efficiency: 50 Arcane provides 75% of max Discovery benefits at 50% of stat investment—best breakpoint for most builds.

Silver Scarab vs Other Talismans: Opportunity Cost

Silver Scarab (+75 Discovery) occupies one of four talisman slots, creating opportunity cost. At 100 base Discovery, Scarab increases Discovery from 100→175, yielding 1.243× drops (+24.3%). At 200 Discovery (50 Arcane), Scarab increases to 275, yielding 1.439× vs 1.301× = 10.6% relative improvement (less impactful than at low Discovery due to logarithmic scaling). Alternative talismans: Shard of Alexander (+15% skill damage, speeds kills by ~8-12% for certain builds), Radagon's Soreseal (+5 all stats including Arcane = +10 Discovery + survivability/damage), Ritual Sword Talisman (+10% attack at full HP, faster kills). For rare drops (<3% base rate), Scarab is superior. For common farming (20%+ drops), damage talismans reduce kill time more than Scarab improves drop rate.

Expected Value Formula for Rare Drops

Worked Example: Magma Blade Farming (1% Base Drop)

Variance & Bad Luck Protection (None in Elden Ring)

Elden Ring has NO bad luck protection or pity system—each kill is an independent trial with identical probability. This creates significant variance: at 1% drop rate (100 Discovery), approximately 13.5% of players require 200+ kills despite 100-kill average. At 90% confidence (9/10 players have dropped), you need 231 kills. The unluckiest 1% of players need 460+ kills. This variance is WHY Discovery investment matters—reducing 100→66 expected kills also reduces variance proportionally, decreasing "unlucky streaks" from 200+ to 130+ kills in worst-case scenarios.

Kill Speed vs Discovery: The Optimization Trade-off

Time-Adjusted Expected Value: True Efficiency Metric

Raw expected kills doesn't account for kill speed. A build that kills in 20 seconds with low Discovery may outperform slow kills with high Discovery. Time-adjusted formula: Expected_Time = Expected_Kills × Average_Kill_Time. Example comparison: Pure Arcane Build (60 Arcane, 220 Discovery): 73 expected kills × 45 sec/kill = 54.75 minutes. Hybrid Build (40 Arcane + 40 Dex, 180 Discovery): 89 expected kills × 25 sec/kill = 37.08 minutes. Hybrid wins despite 22% more kills due to 44% faster kills. Optimal strategy: Invest minimum Arcane for ~200 Discovery (50 Arcane), maximize damage stats for kill speed.

Arcane-Scaling Weapons: Dual-Purpose Optimization

Arcane-scaling weapons solve the kill-speed vs Discovery dilemma by providing both from the same stat. Rivers of Blood at 60 Arcane provides: +120 Discovery (220 total = 1.342× drops, +34%) PLUS top-tier damage (900+ AR with bleed procs). This eliminates the trade-off—you farm faster (high damage) while also improving drop rates (high Discovery). Recommended approach: Use Arcane-scaling weapons for rare farming, allowing 50-60 Arcane investment that serves both purposes. For non-Arcane builds farming common drops, skip Discovery and use pure damage builds.

Ultra-Rare Weapons: Drop Rates & Optimal Routes

Top 10 Rarest Drops & Expected Farm Times

Magma Blade Farming: Volcano Manor Route

Magma Blade (1% base rate, most sought-after rare) drops from Man-Serpents in Volcano Manor. Optimal route: Temple of Eiglay Site of Grace → kill 6 Man-Serpents in Guest Hall (20-30 sec per kill with optimized build) → rest at grace → repeat. At 200 Discovery (50 Arcane + Scarab): 77 expected kills = ~13 runs of 6 enemies = 40-50 minutes average. At 100 Discovery: 100 expected kills = 17 runs = 55-70 minutes. Silver-Pickled Fowl Foot (325 Discovery) reduces to 66 kills but requires constant consumption (600 runes per 3 min = 4,000 runes for full farm, trivial cost). Best build: Rivers of Blood (Arcane scaling) for 2-second kills, making total farm time 25-35 minutes at high Arcane.

Cleanrot Knight Farming: Spear & Scythe Drops

Cleanrot Knights drop multiple rare items: Cleanrot Spear (1.5%), Cleanrot Scythe (1.5%), Cleanrot armor pieces (2-4% each). Farming location: Aeonia Swamp Site of Grace (Caelid) spawns 3 Cleanrot Knights nearby. Problem: Cleanrot Knights are tanky (3-5 minute kills for average players, 1-2 minutes for optimized). At 200 Discovery: 51 expected kills per item = 17 knight clears = 50-150 minutes depending on kill speed. Efficiency improvement: Use Swarm of Flies spell (Arcane scaling, causes bleed) or Rivers of Blood to reduce kill time to 45-90 seconds, cutting farm time to 40-80 minutes total. Alternatively, accept longer farm (2-3 hours) with safe/comfortable build.

Common Material Farming: When Discovery Doesn't Matter

High Base Rate Items: Diminishing Discovery Returns

For items with 15-30% base drop rates (smithing stones, common crafting materials, runes), Discovery provides minimal benefit. Smithing Stone [7] example (15% base): 100 Discovery = 15%, 200 Discovery = 19.5%, 300 Discovery = 22.2%. Expected kills: 6.7 → 5.1 → 4.5. Time savings at 30 sec/kill: 48 sec (200 vs 100 Discovery), additional 18 sec (300 vs 200). This 1-minute savings per stone doesn't justify 50 Arcane investment. Better approach: Unlock Bell Bearings (Sealed Tunnel, Altus Tunnel, etc.) which allow infinite stone purchases at fixed rune costs, eliminating farming entirely. Discovery farming only worthwhile for rare drops (<5% base rate).

Rune Farming: Discovery Has Zero Effect

Discovery DOES NOT affect rune drops—only item drops. Efficient rune farming locations (Mohgwyn Palace Albinaurics: 40,000 runes per 30-second clear) benefit from damage, AOE, and kill speed, not Discovery. Optimal rune farming builds use: (1) Sacred Relic Sword weapon art (massive AOE), (2) High damage stats (Str/Dex/Int/Faith depending on weapon), (3) Gathering multiplier talismans (Gold Scarab = +20% runes, not Discovery). Never invest in Arcane/Discovery for rune farming—it provides zero benefit and reduces kill speed via wasted stat points.

Armor Set Farming: Mixed Drop Rate Strategy

Armor pieces typically drop at 2-8% rates (medium rarity). Full set farming (4 pieces: helm, chest, gauntlets, greaves) requires multiple drops from same enemy. Example: Crucible Knight armor (4% per piece base rate). Expected kills for full set at 200 Discovery: 4 pieces × 77 kills per 4% drop = 308 kills. However, drops are independent—probability of completing set follows complex union probability. Actual expected kills for "at least one of each piece" ≈ 380-420 kills due to duplicate protection absence. Time: 5 min per Crucible Knight × 400 = 2,000 minutes (33 hours). Armor farming is extremely time-intensive—prioritize trading/PVP rewards over farming when possible.

Farming Build Optimization: Stats, Weapons & Talismans

Optimal Arcane Farming Build (Level 125 PVP Meta)

Alternative: Pure Damage Build with Minimal Discovery

For common item farming or players allergic to Arcane builds, pure damage setup: 60 Vigor / 30 Mind / 30 End / 80 Str or Dex (depending on weapon) / 10 Arcane. Use Colossal weapons (Giant Crusher, Greatsword) for maximum single-hit damage, killing most farming targets in 1-2 hits. At 100 Discovery (no investment), common drops (15-20% base) still appear every 5-7 kills, acceptable for volume farming. Talismans: Claw Talisman, Ritual Sword, Roar Medallion, Fire Scorpion—all damage multipliers. This build farms common materials 40-60% faster than Arcane builds due to superior kill speed, accepting ~30% worse drop rates on rares (trade-off not worthwhile for rare farming but optimal for common materials).

Edge Cases: Rare but Important Scenarios

New Game Plus (NG+) Drop Rate Consistency

Cooperative Multiplayer: Drop Sharing (Does Not Exist)

Unlike some games, Elden Ring does NOT allow drop sharing between players. When summoned cooperator kills enemy, only the cooperator receives drops—host receives nothing (vice versa). This prevents efficient "group farming" where four players farm simultaneously. Each player must farm individually. However, cooperation can speed farming indirectly: (1) Summon helps kill tanky enemies faster (Cleanrot Knights, Crucible Knights), (2) Host still gets loot from kills they make, cooperator speeds kills via aggro management and damage. Expected time reduction: 15-30% faster kills with skilled cooperator, partially offsetting solo farming. Still less efficient than solo farming at optimal build/strategy due to cooperation mechanics overhead.

Item Despawn Mechanics: Loot Permanence

Dropped items persist indefinitely on the ground until picked up or 100 item limit reached (oldest items despawn when limit exceeded). For farming: Kill 50 enemies without looting → all 50 drop pools remain → collect all at once. This allows "batch farming" where you clear large areas, then loot everything simultaneously (faster than looting each kill individually). Example: Man-Serpent farming—kill all 6 in Guest Hall → rest at grace → repeat 10 times → collect 60 drops at once. Saves ~2-3 seconds per kill on looting animation × 60 kills = 2-3 minutes saved. Minor optimization but compounds over hundreds of kills.
