Minerar

Mining yields different materials depending on the rocks you mine, with different rocks belonging to different biomes. However because of spawn behavior rocks (except for gem rocks) can sometimes be found outside their biomes.

Mining Chance Formula:
5% + (Mining Level × Pickaxe Modifier)%

It appears everyone starts with a 5% chance to mine, which increases approximately 1% per level (but still just shy of 100% at level 100 mining). Pickaxes apply a multiplier, lowering the mining cap depending on the type of pickaxe used.

(Different pickaxes require higher character levels to equip, as noted in the second column.)

Mining Bonuses
You can also enchant items with a bonus to mining using citrine, quartz, and sapphires.

Rock Yields
Different rocks can be better--or even unique--sources for different materials, as detailed below.

Desert Rocks
Found in the sand biome; prime source for stone, minerals, and precious metals.



Plain Rocks
Found in the grass biome, a common starter rock that offers little besides stone and flint.



Black Rocks
Found in the snow biome, these rocks are a significant source of obsidian.



Gold Rocks
Mainly found in the Underground, these rocks are very rich in minerals and precious metals.

Crystal Rocks
Only found in the Underworld, a highly sought-after source of gems for Enchanting.
