Rock Golem

Rock Golems are powerful Hardmode enemies that spawn in the Cavern layer. They hurl rocks at players that are out of contact range.

The Rock Golem drops Stone Blocks on death. Along with gem trees, they are the only renewable source of Stone Blocks in a world.

Trivia

 * The Rock Golem may be inspired by the Earthshapers from the Spyro series, as they are both grey bipedal rock monsters with flowers growing on their head.
