Fun fact: you can skip most of the annoying experience by going dimension door hopping. After a few triesSirocco and acid fog, with something like tar pit to hold them inside. Polar midnight if you have it. Layer the field & then initiate combat by a fireball or another long range spell, to lure them into the mass aoe spam.
Thanks for the Acid Fog tip. Easier when there are chokepoints. The other one where you're stuck in the big room, I had to spam 4 Siroccos to win.
Jaethal, my oh so special winged sorceress, managed to hop into Nyrissa's room and trigger the cutscene, which teleported the rest of the party in.
