Bone golem

Created by demented wizards, bone golems are generally used to guard prized possessions. Their bodies are pieced together from various creatures, both humanoid and monster.

Special abilities
A bone golem has 20/+2 damage reduction and 50% immunity to both piercing and slashing damage, as well as the usual construct immunities to critical hits, death magic, disease, level drain, ability drain, mind-affecting spells, paralysis, poison, and sneak attacks.

A bone golem can use its fear howl three times per day.
