Notes[]

Old One's Skeletons are rather fast compared to the other members of the Old One's Army. Combined with their low life, this makes targeting them an ideal tactic.
Unlike the Dark Mage that summoned it, the Old One's Skeletons are capable of entering an ethereal state to freely fly upwards and pass through tiles, if needed.
Like other members of the Old One's Army, the Old One's Skeletons are immune to Teleporters and Lava, and will take half damage from Traps.
Unlike most skeletal enemies, Old One's Skeletons can do damage to the Skeleton Merchant.

Trivia[]

The Bestiary entry for the Old One's Skeleton: "Small armies of these skeletons are summoned from the ground by Dark Mages, loyally serving their master's will."
