Ok, I beat Sarevok on normal, now you can be satisfied Borys

What I did:
Part 1:
-Lured Semj who is the main guy that fucks my party with chaos down from the right hand side solo
-Imeon shoots arrow of dispelling on him
-party + summoned monsters flank him and fuck him up
Part 2:
-Tried to do the same with Angelo on the left side but it aggro'd Angelo + Sarevok at the same time
-Angelo shot his dispel magic to everyone
-Had everyone drink an oil of speed (haste)
-SOMEHOW MC PALADIN + JAHEIRA GOT CONFUSION. I DON'T KNOW WHY
-so they just sat there
-Angelo + Seravok comes down
-Had Imeon shoot an arrow of dispelling on Angelo
-party + summoned monsters flank Angelo while whoever is targetted by Seravok (was Dynaheir) runs away
-Kills Angelo pretty quick but by now most summoned monsters are dead
-Seravok turns to Minsc and starts fighting him 1 on 1 and kills him, then turns to Khalid.
Part 3:
-MC + Jaheira frozen in place with confusion (fuck u game)
-All summoned monsters outside Nymph dead
-Dynaheir down to like 1 hit until death on left side
-Khalid & Nymph tanking Sarevok
-FLAME HORROR SPAWNS AND RUNS OVER AND STARTS WHACKING CONFUSED JAHEIRA
-Dynaheir spams paralyze wand on Sarevok
-IT FINALLY WORKS ON SAREVOK WHEN KHALID HAS 1 HIT UNTIL DEATH
-Nymph disappears
Part 4:
-MC + Jaheira still frozen and useless goddamnit because somehow confusion hit them and Battle horror is beating up Jaheira slowly to death
-Sarevok paralyzed in place
-Khalid (1 hit away from death, hitting Sarevok for about 10-12 damage per attack) + Imeon (even arrow + 2 with bow + 2 is only doing 4 dmg which is being resissted for 4 dmg so I switch her to a +2 dagger and she's doing 6 dmg with 4 dmg resisted) + Dynaheir (1 hit until death and out of all attack magic after a few magic missles, so throwing sling shots) hitting paralyzed Sarevok hoping to kill him before A) Sarevok wakes up and kill Khalid in 1 hit and then Dynaheir in next hit and then Imeon and B) before Flamehorror kills Jaheira and then goes and kills frozen confused MC for game over.
This goes on for like 5 mins. Sarevok was at like 1 bar the entire time. How long hitting him for 10dmg + 6dmg + 4 dmg does it take to do that final 1 bar.
Battle horror kills frozen Jaheira and starts wacking on MC. Now if MC dies game over, Sarevok unparalyzes game over.
Luckily Sarevok
finally fucking dies.
The end.
