Help with Greenmist quest

[calloflunacy]

On the final part of the Greenmist quest, and I have my Charasis key. I need the mirror of self loathing off Drusella, but she has a 24 hour timer and wiki says she's fairly contested. Not sure who to talk to about when she would be up, but if anyone goes down and does the fight regularly I would like to tag along just for the mirror if possible.
