Finally was able to beat him after quite a few trys... I leveled to 4, laid down traps I had gotten from the dungeon, took out the mage first, then used aloth and used the fire cone spell and took out the priest and ranger (lucky I think, did a 80 and 70 hit), from there I took out the champions one on one. I did fairly well I think, only lost my barbian. Also useful was the spirit I summoned with my main chanter.
