Bone Prison is the third and last defensive skill of the Poison & Bone skill tree. It works just like Bone Wall except it surrounds and traps anyone, even yourself, in the middle of bones. It is a very useful spell if you decide to level it and use it wisely, it can serve as a better Tank than Golems.
Bone Prison can't trap Wraith monsters and some monsters can shoot projectiles through bones.
The Hit Points shown below are only for Normal difficulty. The Bone Prison hit points increase for Nightmare, and again for Hell Difficulty.
It is also an attack Diablo uses against you when you cast a town portal too close to him, though it is marked as "An Evil Force." In Diablo III, he uses this attack to trap your Follower prior to the final battle, forcing you to fight him alone; as well as using it as one of his main attacks during the battle with him. If you get caught in Diablo's Bone Prison, he will grab you by the throat and drain you of your Life before slamming you to the floor.
Similar to the Bone Wall, a Necromancer with this skill can summon a spirit wall of bone in the form of an enclosing ring. This prison traps all enemies within its circumference. Imprisoned within a cage of bone, the captives are held helpless until they can summon the strength to break through its skeletal confines or the Necromancer loses his hold over the spirits.
