Bone Prison is a Necromancer Skill in Diablo 2. Bone Prison is part of the Poison and Bone Spells Tree and requires level 24 to be unlocked. Skills usually define a character's playstyle and are divided by Class and Skill Tree. Some Skills have synergies, which provide benefits to other skills on the same Skill Tree.


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.
