The Spirestone Butcher is a level 57 elite rare mob ogre found in Lower Blackrock Spire.
He patrols in the hallway leading to Highlord Omokk, leader of the Spirestone tribe. Because he patrols alone, as long as you've cleared the first three ogres you'll see as you come down from the main instance entrance, he's an easy fight. If you're not careful, he can become an add to that first three-ogre fight, making him more challenging. He hits hard but goes down quickly.
