Alrik means the wisdom skill..it gives you more exp wen yu kill any creature.
Id say the mage is easist....when i had killed the necro at the bottom of the dungeon...i easily picked off all the other strong types....skeleton guardian etc.i dont now if poeple realise this but when you get surronded by all those skeletons for killing the necromacer...there are still some strong types remaning on the edge of the walls..you have to actualy seek them out...if you run and mardanues comes and saves you...thats that..they dont appear if you return again.
