I had about 34-35 level and yes, they killed me in a few seconds. The divine did, mainly. So to win this battle being a ranger I maxed out my Invisibility spell quickly after finishing the conversation (had about 15 undistributed skill points to that moment) and used it so it gave me time to think and to find the most unpopulated corner. Then I summoned my necro pet (8 lvl mage spells, 5k hp), then just ran around the room using blasting arrow spell on whoever when ready. Then stun arrow spell on the divine when all the cannon fodder was dead.
