How rock luck works
1
Effective luck = pickaxe luck × rock luck × (1 + all % bonuses). Only ores at 5% base chance or rarer are luck-boosted.
2
Every rock has a fixed drop table and HP — the timer adds the swing cycle plus a 1.5s respawn gap.
3
Pick a target ore and quantity to get expected rocks and total farming minutes.
Frequently asked questions
Does pickaxe luck help for common ores?＋
No — luck multipliers only apply to drops at 5% base chance or below. Common ores keep their weight, so farming commons is pure speed, not luck.
What is the best rock to farm Mythril?＋
Mythril drops from Forgotten Kingdom crystal and vein nodes at low base rates — stack a Mythril or better pickaxe with a Luck Totem to roughly double its effective weight.
Why does the calculator say my pickaxe is too weak?＋
Every rock has a minimum mining power requirement. Below it you cannot mine the node at all — upgrade the pickaxe first, luck second.
