Boulder

Boulders are large rocks commonly found in Savannas and Rockylands, although they may appear anywhere in the world. Their main purpose is to provide Rocks which can be used to build a number of objects/structures. A single Boulder will drop 3-4 Rocks and at least 1 Flint. Additionally, Boulders may also provide Gold Nuggets and Nitre. Boulders do not respawn meaning that Rocks, Flint, and Nitre are non-renewable resources (they will eventually be completely used up).

Mining
Boulders can be mined using the Pickaxe. To do this, simply click the Pickaxe on the Boulder or equip it from the belt by right-clicking. Once Wilson has begun to swing the pickaxe, either the LMB or Spacebar must be held to continue mining. Boulders will slowly reduce down while being mined until they are completely destroyed after 6 strikes; at which point they drop their resources.
