Estimate boss runs, dungeon clears, and farming time for rare Lineage Piece drops.

Estimated farming target45 runs about 1.13 hours

Formula

This calculator uses runs = ceil(log(1 - targetChance) / log(1 - dropChance)). It does not claim hidden Lineage Piece drop rates. Enter the rate you trust from your own testing or a current source.

Best Use

Use this before long boss farms, Shadow materials, outfit drops, or dungeon key routes. The result is a probability target, not a guarantee.
