Just curious, I finally beat this motherfucker after like 2 straight hour on the hardest difficulty.
The main reason it was so hard was because non of my +4 weapons could hit him.
Something happened in the fight that suddenly meant that I could, after like 2 hours of breaches, lower magic resistances, pierce shields, remove magics, dispels.
What did I do? I suddenly noticed Jan could hit him and was like "Don't question it! Kill him NOW!"
Glad he's dead but feel a little hollow because I don't know how.
I used the level 9 blades spell/sword thing too that *maybe* drained his levels?
