Mining

Every rock gives you its stone. On top of that, each rock has a chance at a special find, like coal, ore or a gem. Bigger rocks take more hits but have better odds.

Bigger rocks, better loot

Rock size	Hits to break	Special find	Extra copy
Very small	3	9.8%	20%
Small	6	14.5%	30%
Small tall	9	17.2%	36%
Medium	12	19%	40%
Large	15	23.5%	50%
Huge	20	27.8%	60%

"Hits" is with a normal Pickaxe. Pickaxe: 1 damage, Iron Pickaxe: 2 damage, Orichalcum Pickaxe: 3 damage, so better pickaxes break rocks 3x faster.

What's in a special find?

A special find is either coal or a cluster (12% base), or one pick from the list below (8% base). Here's how that pick splits up:

Good to know

Level up mining and ore and gem finds get more likely: +0.4% for each level, up to +6%.
Critical hits: each mining level gives a 5% chance to hit twice as hard (up to 50%).
Iron Rocks always drop Iron Ore, with a 25% chance of a second one.
Luck from food and hats gives a chance at a rare ore or gem on every rock once you have 10 luck or more.
