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 when mined. Additionally, Boulders may also provide Flint, Gold Nuggets, and Nitre. Boulders do not respawn; however, Rocks, Flint, Gold Nuggets, and Nitre are renewable resources because they can be found after Earthquakes while underground.

Mining

Most kinds of Boulders can be mined using the Pickaxe, Opulent Pickaxe, or Pick/Axe. To do this, click the tool on the Boulder or equip it from the inventory by right-clicking. Once the character has begun to swing the tool at the Boulder, either the LMB or Spacebar must be held or continuously clicked to continue mining.

It takes 6 strikes to mine a Boulder with a Pickaxe and Opulent Pickaxe, and 5 with the Pick/Axe. It depletes a normal Pickaxe's durability by 18%, Opulent Pickaxe's by 4.5%, and Pick/Axe's by 4%.
