In the Duchy of Hinclloinpe ruled by a Confederacy, a character must undergo a Trial by combat.
He has been framed by A monster or group of monsters - mind flayers, a beholder, giants, a dragon - and if found guilty of Treason, his punishment will be Resurrection. You just need a portion of the creature’s body to bring them back to life. So, kill the prisoner and bring them back when their sentence ends. There’s an expense of 10,000 gp, but a wealthy family might be given annual Resurrection privileges for an hour or so if they pay the bill.
