This right here appears to be what I was missing. No Dragon Thrashes but the niche + chill fog let me whittle them down a couple at a time. Thanks again for everybody's help.

Alright started the forge fight and I'm about done with all of this. Entire party dead in 10 seconds no matter what I do. Obviously there is some strategy involved here that I'm completely unaware of but hell if I can see it.

Thanks everyone for your advice. I now stand victorious, adra disc in hand. It looks like just entering that room triggers the ambush even if you don't take the disc (but the traps don't spawn). I re-geared for the encounter and when the ambush triggered I used all the summons I had to block the one group and retreat to a choke point to deal with the other. Ectopsychic echo and Amplified Wave works extremely well on spirit enemies. I also found the higher level shock aura Durance can cast is decent if you can cast it on a pile of summons. Those Battery Sirens are still an absolute bear to deal with. Any suggestions for them? Devil is great at carving them up but i find she dies in a couple of hits (though maybe I'm utilizing her poorly).

Is there some sort of trick to dealing with spirit enemies in WM1 (on hard/upscaled) that I missed? I'm stuck in the room with the adra disc and can't go any further. The Battery Sirens in particular are really destroying me as they seem to be immune to everything. I'm so frustrated I'm probably going to knock the difficulty down to easy for the time being. I have Aloth and GM focused on debuffs, Devil and Maneh for damage and Durance buffing the party. My party is level 11 and composed of: Tanky Chanter Aloth Maneh Devil of Caroc Grieving Mother Durance Any advice would be much appreciated.
