To complete the bishop's quest, you must find the golden chalice and return it to the bishop. The problem is, to get the chalice you must kill the Champion of Blood. When he dies, a greater hellion bursts forth from his corpse. This is one nasty dude. Expect to take a group of half a dozen level 20 or so characters to polish him off. If you kill him, he will drop the chalice and a glowing red amulet.

Take the chalice to the bishop who will give you a jade amulet (casts cure poison) and white satin gloves (casts major healing) for your trouble. The glowing red amulet opens a room north of the dark wizard which contains a massive chest which drops boatloads of cash and some cool items.
