Forum:Archon with a cockatrice corpse

Help, my Healer is stuck in a corner on the Plane of Air, getting hammered by an archon with a cockatrice corpse. I can hit him with +7 Mjolly, but I have get stoned every turn and have to stop to eat lizard corpses, which I'm almost out of. I'm wearing a ring of conflict; what can I do to kill him or escapeQ.
