Skeleton

Skeletons are Enemies that spawn in the Cavern layer. They follow the Fighter AI, and can open Doors. Unlike Zombies, they do not require a Blood Moon to do so. They can drop a Hook which is essential for crafting a Grappling Hook, though other Hooks can be acquired through other means.

Skeletons are immune to Poisoned and Venom Debuffs.

In Expert mode, some skeletons throw bones which deal 2x their base melee damage (also multiplied by 2 due to it being expert mode, making the damage 4x the normal mode base damage as shown below).
