Well after several weeks I managed a win with a mere 2 deaths both in the final fight. I came close to death so many times during the game that if I had died it would have been just a matter of a few points difference. Many defensive abilities + some luck and occasionally good tactics (or at least not stupid as heck tactics) helped.

The final fight was insane. Earlier, I read something on the forums or here, about doing the orbs at the 4 corners but I didn't quite understand how to work it (There is no real reference in game that I could find and the journal notes were not helpful) so I just went with as defensive a posture as I could muster (Barrier, Providence, Circle of Warding and Sanctity + various heal spells. Totality was very helpful here.) Slowly, I weakened the sorcerers with AoE spells and DOT effects. An enemy DOT finished off one of the bosses for me. (Thanks mr fire U guy.)

Sadly the Sun Paladin died fairly quickly but she accounted for a good amount of damage off one of them. The other was fairly hard to kill and the monsters summoned from the portals were painful but no where near as much as the two bosses. 7500 hps! ouch. The most annoying thing was the mimicry effect, where I cast something and had it cast right back at me.

I think this particular character took me 4 days? to play from beginning to end. I know there is much more to do (spellblaze, elven ruins, one of the eastern quests I didn't complete (Important News?).

This is the first win in any TOME for me so perhaps it isn't quite as hard as it used to be, but for me that is a good thing. I know there are plenty of purists who deem multilife wins to be worthless but it was a challenge for me. I expect my next character to die miserably a lot before I learn how to use it's abilities.
