Butchery is a skill that causes the player to automatically butcher edible corpses when you walk over them. This behavior can be toggled on and off in the abilities menu. There is a small chance to receive rarer items when butchering.
Butcherable Items Edit
In earlier versions of Caves of Qud, Butchery could be upgraded to Masterful Butchery through purchasing an additional skill, allowing special items to be obtained from some corpses. This effect was eventually merged into Butchery and you always have a small chance to receive rarer items from butchering.
