Well I finally defeated Firkraag after 3 hours I think... (Thank god, he was tough.)
I kinda semi-cheesed it to beat him. Used wand of cloudkill (only the wand with 6 shots) so I softed him up and he was still in 3/5 bars of health. And still even then he destroyed me most the time. So here is what I did...
My Party (Who was hasted 100% of the time)
CHARNAME (Paladin) - Melee & Tank & Healer (It was most effective when Firkraag was targetting CHARNAME most of the time so I just attack while I'm constantly healing myself and the others can just lay on the hits.
Keldorn - Melee & Dispelled Firkraag
Anomen - Melee
Viconia - Dispelled Firkraag & provided buffs and heals and attacking once in a while
Hear Dalis - Magic Missle/On and off Melee as well with default swords and buffed his CON up
Jan Jansen - Magic Missle and ranged attack with piecing arrows.
Once Firkraag was 1 bar left. Everyone rushed in with haste and he didn't stand a chance. Keldorn was the only one that died which broke my rule. But Firkraag was really hard and just killing him was good enough. I restored Keldorn, Got the Carsomyr sword for myself and I was glad.
How do you guys normally beat him? I know some people have done it so easily with level 12 character/solo and I'm just in shock because Firkraag was hard.
