Iron Soul: Dungeon Race Reroll Simulator & Forge Cost
Simulate Race Reroll pulls using the published drop rates, track your pity counter toward a target race, and calculate forge ore costs. All randomness uses Math.random — for strategy, not prediction.

Forge Ore Cost Calculator
Calculate total ore needed to craft N pieces of an equipment category.
3 ore per craft × 1 craft = 3 total ore.
Listed success rate: 100%. Mixing ore types shifts the crafting pool — see the Forge & Ores page for documented mixes.
How the simulator uses drop rates
Each roll is a weighted random pick from the 13 races in Iron Soul: Dungeon using their published drop rates. The observed rate converges on the expected rate as you increase the number of rolls — at 100 rolls the variance is large, at 10,000 it's usually within ±0.1%. The max pity counter is the longest streak of misses between target hits; the practical cap depends entirely on RNG.
Drop rates are sourced from the cross-checked community trackers (Sportskeeda, earnaldo, allthings.how, bloxodes, mrguider). Approximate rates may shift across patches — confirm in-game before spending Race Rerolls.
