from what I saw of it (it not in my codex because of using a different save file) it did look interesting though I don't know how much use the dragon would get out of it, but the sorc or wizard could find real nice use of it. I never did try with a different class but I might go ahead and try with a sorc and see if he will work, though from what I remember the 4 generals really hate magic (retaliate, 50% mr + 4 death protections, and ensnare on three different guys)
edit: never taking mystic balance in phantom citadel again because 4 mana leemisis doesn't work. good news is though sorc went better than expected as slayer wand pulled some heavy weight along with cydstep (made me able to take a hit from phase 1). also never noticed +1 hp regen when i first saw it. also those daggers have no effects i'm assuming.
