Got a low level thrall that’s just been replaced and you don’t know what to do with him? CRUCIFY HIM!!!
Did you take a bearer thrall just to take her pack and are unsure where to put her? CRUCIFY HER!!!
Crucifixion is a major lore piece in this game, and players should be able to crucify their thralls on a whim even if it’s just for decoration. Show the enemy how much of a cold-hearted tyrant you are!
