a sentenced prisoner  

This is the guy you have to keep from dying in the Trial of Execution. Bunches of mobs appear along with an executioner, you have to kill 3 waves before the executioner becomes targetable. If you don't kill the waves fast enough, he reaches this guy and kills him. If the executioner gets to this guy, forget it, because being level 1, he has the hit points of wet tissue paper. Kill em fast.
