Mithril Luck
Mithril Luck improves the hidden progress meter for damage-based mithril drops. It is not a flat drop percentage. It makes each qualifying hit push the meter farther, then the game checks that progress against a random step.
| Formula | Each hit adds progress from its damage share of mountain max HP. The multiplier is 0.03 + 0.06 times the capped mithril-luck term. |
|---|---|
| Cap | The formula caps the combined mithril-luck term at 18 before applying the multiplier. |
| Normal luck conversion | Each normal luck point on the hit contributes 0.01 Mithril Luck for this formula. |
| Best use | Take it when mithril is the bottleneck and damage drops are part of your income plan. |
How To Read It
Section titled “How To Read It”The practical formula is:
Mithril progress per hit
Progress scales with damage dealt divided by mountain max health, then multiplied by a mithril-luck factor. A drop occurs when accumulated progress beats a random step from about 0.3 to 1.7.
This means Mithril Luck is strongest when you are already landing meaningful hits. If your damage is tiny relative to mountain health, Mithril Luck helps but can still feel slow. If you need guaranteed mithril now, combine it with dens, Mithril Veins, and Spelunkers.
