Dwarf

Dwarves are friendly mobs that spawn commonly in the Living Rock Caverns. They are short humanoids who are there for the same reason as you - to get lots of gold! They are responsible for the many mineshafts in the dimension, and are willing to trade with you. They will give you an iron pickaxe in exchange for a gold ingot, allowing you to stay and mine for longer. If attacked, they will turn hostile and attack with reasonable power. They are very fast due to their size, so do not underestimate their fighting ability. When killed, a dwarf will always drop a gold nugget, and occasionally a gold ingot.
