Demon Skeletons

Demon Skeletons are undead monsters that live in the deepest dungeons of Noverum. Nobody knows where these creatures come from. They are much stronger and faster than normal skeletons - from which they differ externally only by colour. Like them, they can drain life energy off their opponents.
Demon Skeletons have 400 hitpoints. They are immune to fire, poison and they cannot be paralyzed. It takes 620 mana to summon or convince these creatures.
Demon Skeletons yield 240 experience points. They carry gold coins, torches and sometimes other items with them.
