Bone Golem

Magic Vulnerabilities (su) - • Magical effects that heal living creatures slow a bone Bone Golem (as the slow spell) for 1d4 rounds (no save). • A magical attack that deals negative energy damage breaks any slow effect on the Bone Golem and heals 1 point of damage for every 3 points of damage the attack would otherwise deal. If the healing would cause the Bone Golem to exceed its full normal hit points, it gains any excess as temporary hit points. A bone Bone Golem gets no saving throw against attacks that deal negative energy damage. • A resurrection spell negates its resistances and immunity to magic for 1 minute.

Immunity to Magic (su) - Immune to any spell or spell-like ability that allows spell resistance. In addition, certain spells and abilities function differently against the creature, as noted below.

Construct Traits (ex) - Constructs cannot heal damage on their own, but often can be repaired via exposure to a certain kind of effect or through the use of the Craft Construct feat. Constructs can also be healed through spells such as make whole. A construct with the fast healing special quality still benefits from that quality. A construct cannot be raised or resurrected.

• Melee (Natural) - 1 x bite +14 (1d8+4). Reach: 10 ft.
• Melee (Natural) - 2 x slams +14 (2d6+4). Reach: 10 ft. Bone Prison - Thrown bones magically duplicate and form a cage surrounding struck creatures who are then Grappled. Each round, the cage makes a combat maneuver check to deal the Bone Golem's slam damage. If the check fails, the target is still trapped but takes no damage. The target can escape the grapple normally, or can break out of the bones by dealing 15 points of damage to the prison which has the same AC, vulnerabilities, weaknesses, and saves as the bone Bone Golem itself. Damage to the prison has no effect on the Bone Golem. The Bone Golem can only have one bone prison active at a time. If it wishes to create a second one, it (or some other creature) must first destroy the existing one.
