You can kill her easily, the only things that aggie are the Cursed spirits and corpse crawlers, if you pull from the top of the ramp before you enter the pit you can kill her and sprint out without getting killed or even hit. The warriors and Commander (not the one with the dog that roam he is different) will spawn below and you don't have to clear them out or fight them to pull her or make her respawn, however they are nice exp while you are waiting and can be taken one and two at a time.
