come back when ur level is higher, together with ur creature.
frankly, i don't have trouble at all during this quest. my creature is doing 99% of the job for me. I used quite a high lvl goblin ranger's head for my creature (with fireball lvl 8/9 i think).
its fireball can wipe out most of the creature with a single blast.
so, try upgrading ur creature. ur creature's lvl depends on your character's lvl. and more importantly, finish your necro's mission cuz it will significantly increase the power of ur creature. then ur creature will be the second most powerful being in aleroth. after urself that is
