Does anyone have any non-cheating tips for getting past the clusters of harpies and bears in the dungeon of totlm? I am finding it very frustrating. Thanks.

All i did was use summons and maybe a wall of moonlight spell.

The bears seem to be vulnerable to charm and or the animal charm ring and I like recruiting help from the enemy.
The harpies are nasty and the only tactic for me was any magic resistance I could find and repeated trips in and out to heal and back in.
