From what we've experienced, the adds can't be hit with AEs, only single target damage. Whenever I cast any of my AEs during the fight, I receive "No targets in range". Same for my wife, an AE-happy 'lock =)
Usually at work when I post so no access to SS.
Pretty much as mindeen said. Couple of Clarifications.
She's only triggerable after Hoarfrost is dead.
2 adds spawn for every one killed. but until maiden is at 10% killing adds is the ONLY way to hurt her. Pick a main assist and either burn them down one at a time, or go crazy with the ae's then finish off low hp adds with single target damage.
At 10% swap to single target burn on the maiden and she'll drop, dont AE down more adds or there's a chance your tank could get overwhelmed (aggrowise more than anything else, healers getting hit is never apreciated ). Don't remember killing the adds after the kill so i #think# they de-spawn.

Good info to know, you rock Mindeen!
