Skeletons are commonly found throughout the cathedral section of the labyrinth, and some appear in the upper catacombs as well. They are the lowest form of undead encountered in the game, alongside with Zombies.
There are several types of skeletons in the game. In addition to these regular skeletons, there are also Skeleton Archers and Skeleton Captains, the latter of which are tougher skeletons who use shields. Skeletons are fragile monsters and will easily disintegrate, but are always immune to magic damage, with the exception of Holy Bolt.
