Mining

“Mine rocks for ores. Every so often the stone gives up a gem, and rarer things still for the patient.”

Every skill uses the same XP table: 951,207,314 XP for level 99. Past 99 the XP keeps counting.

How it works

Pick a rock from the list (you can pick any you have the level for). Every key press or click is one try at it. A try that works gives you one of what you picked, straight into your bank, plus the XP below. Nothing is random about what you get (some food can double it, and rare finds roll separately): only whether the try lands.

Your chance per try is the same for every rock: 30% at level 1, plus 0.5% for every level after that, plus your pickaxe's bonus, up to 100%. With no tool that is 79% at level 99. With an Infernal Pickaxe (+35 points) every try lands as soon as you can wield it (level 80).

Tools

A tool sits in its own slot in your skilling loadout and only works for Mining. Its XP bonus multiplies every bit of Mining XP you earn; its success bonus adds straight to your chance.

Tool	Mining level	XP bonus	Success bonus	Chance at 99
Bronze Pickaxe	1	+5%	+7	86%
Iron Pickaxe	15	+10%	+12	91%
Steel Pickaxe	30	+15%	+18	97%
Mithril Pickaxe	55	+20%	+24	100%
Adamant Pickaxe	70	+22%	+27	100%
Rune Pickaxe	80	+25%	+30	100%
Infernal Pickaxe	80	+30%	+35	100%

Dwarven Stout raises the level used for your chance only (never your XP, what you can pick, or pet odds), up to 99.

Rare finds

Rolled on every success, each on its own (and, with the Agility perk Sharp Eyes, on some misses too). Gear and food with a rare find bonus raise these odds (a +10% bonus makes a 1/200 find a 1/182 one).

Find	Chance per success	Where
Uncut Gem	1/200	Anywhere
Onyx	1/1,000,000	Anywhere

Pet

Rock Golem is rolled on every success, at 1 in (30,000,000 − 25 × your level): 1/29,997,525 even at level 99, so it's normal to get there without one. Rare find bonuses raise the odds a little.

Fastest XP
