Who uses Bone
Bone is a body armor runeword intended for Necromancers. It offers a small set of useful mods: skill levels, a large mana boost, and resistances. The chance to cast Bone Armor when struck will replace any existing Bone Armor, so it is not a stacking defense. Although it requires two Um runes, which some players find costly, the runeword is easy to assemble and the overall bonuses can work for many characters. It becomes available at level 47 with three sockets.
