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.

In, certain Skeletons throw bones which deal 2× their base melee damage. The damage is further multiplied by 2 due to Expert's general damage enhancers, resulting in a damage 4 times the base value.

Trivia

 * Skeletons appear in more than 50 different forms in the game:




 * The internal name of the Astronaut Skeleton is misspelled as "SkeletonAstonaut" in the game code.
 * The original Skeleton's head sprite remains used in the game for the Skull Lantern and Mechanical Skull items.
 * The Skeleton Banner appears to also be based on the original sprite of the Skeleton.
 * The Carton of Milk dropping from Skeletons is probably an allusion to the fact that like milk are rich in, a chemical element whose ions are important for bone formation.
