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.

When being attacked, they continue to attack, making stun-lock options unusable.

Trivia

 * The Rock Golem drops the second most coins of any non-boss enemy, tied with the Nymph, Pirate Captain, and Paladin, and the most of any enemy that is not considered rare by the Lifeform Analyzer, second only to Mimics.
 * The Rock Golem and Gem trees are the only renewable source of Stone Blocks in a world.
