[Spoilers] The final battle, A little too hard for me :( Options

[Anomaly]

Hello,

I have successfully beaten the tatooed man at the Friendly Arm and his little army of wind horrors and undeads... one by one, thanks to this nearly-invincible Flamming Fist Elite's unit with great thac0 and unlimited cure critical wounds spells... although he failed once his morale check, and I was in big trouble Wind horror in particular have such a great Thac0, I doubt it is possible to kill them without using the guard as a meat shield.

I have also beaten the high sorceress on the top of Friendly Arm Inn without too much pain... thanks to my wands.

I am now in Beregost, teleported into that large room. I awake in a corner, far from Teven and the two high sorceress. A Big Thanks for that, it allows me to save right after the cutscene and before the battle (it's bloody annoying when you have to watch a cut-scene or choosing dialogues options before a battle at each reload).

But I cannot kill any of them. I can even hardly hurt them before I bite the dust.

Teven have lots of hit points and a extremly good Thac0 : even with ctrl-y the two sorceresses I can't kill him without loosing most of my party. And with the sorceress and their mass dominate spell, I am really helpless. I do not forget their globe of invulnerability (my dispel magic failed to dispel those), which made them immune to most of my magic. My wands did nothing either.

I have tried to drink two potions of magic resistance to get 100% immunity to magic, but with the sorceress's ability to teleport away and attack my group, this is not a winner strategy. I am thinking to either a) drinking my all 10 potions of magic resistance and using one protection from magic scroll to get all my party immune to magic, or ctrl-y three times

Any hint for this battle would be very welcomed.

PS: I am playing the Bg1Tutu version.
