Just killed him with a 52 ranger (myself), 48 ranger, 52 cleric, 51 chanter and a 34 wiz, and he wasn't that hard to kill. He droped the key for 7th floor and a Talisman of Vhal Sera (2ac 4cha 3wis 3int, neck) for brd shm nec mage wiz ench, and it's lore no drop.
All in all, a good time was had by all.
