- Armour - In the heat of battle, skeletons can raise their defence with this armour spell.
- Lightning - In the first Dungeon Keeper game, skeletons that reach Level 10 can attack by casting lightning bolts from their swords.
- Undead - Being undead, skeletons are immune to poison gas traps.
Aside from battle, skeletons don't like anything. When they are not training, they are best put to use on guard posts.
Skeletons do not get on at all with bile demons and the two creatures will attack each other if the Keeper does not take care to keep them apart.
