BAAL on impossible

[sahibjacek]

I play mage and now I am on 53lvl (24At, 43Def, 66Int after using scrolls) with 31000 command points (on impossible level of course). And I CANT'T kill Baal. My greatest succes was in third battle attempt when Baal in 29 round had 71K HP left (if I remember he started with 253K HP). Problem is that I have not Mass Haste spell. Its unbevielable but in ALL damned world I cant find this scroll! . I tried human army with Paladins, Knights, Cavalry, Inquisitors and Griffins. Of course Stone Skin and God Armour is very usefull, Geyser works perfect for Baals mass summonning but... but I cant deal with this mass summoning. When Baal was weaker he summonned demons almost every two rounds! In 29th round he summoned few hundreds imps, demoness and demons and (what was more worse) about 40 archdemons! For my tired troops that was end. I know that much players killed Baal having similar hero like me but now I should think that this is impossible. Maybe someone give me a good advice how defeat this ugly, dirty, stinky piece of red meat
I will be deeply gratefull!!!
