A Bone is a menacing undead warrior that wields a sword made from a thigh bone. They appear as nothing more than animated skeletons with no skin, muscle, or flesh. The magic that animates Bones is relatively weak, and the Bone can be destroyed by even minor physical attacks. It is also weak to Fire and Harm spells, though like all other undead it is immune to many mind-damaging spells and to Ice attacks.
Bones are typically found guarding low-level dungeons, such as the Temple of Fiends. Occasionally they wander outside into the surrounding areas.
