Currently I try to solve the Ethel problem in Act 3 once and for all; I was badly prepared for the encounter, only tactical retreat helped me (I didn't know anything about the fight before start). I will try to control her maybe as an alternative approach next time, before she creates another million of copies. If it helps, I will praise control spells forever.
Putting her friends into hold person definitely helped me in this one - along with having a very hearty breakfast. I haven't tried HM yet though.
