well i reached the battle with Uladar Maritarius and there is no chance to beat him because of the unbalanced skill system.i`m level 4 and only bad skills were rewarded for gaining level.i attached 2 screenshots.you need to work at skills system because it s not doable , at least on impossible level . and i finished with all classes wotn on impossible.I destroyed all the avaialable enemies on the island so i only have Uladar now.
