ToME: the Tales of Maj'Eyal

Thanks for the replies, I missed them when I was playing because I wasn't sure my post was approved (was taking quite long) so I stopped checking the forum. I did go on to win Tome 4 with this guy, my first win in a roguelike! Made me very happy. The last fight was hellish and left me one step away ...

Playing Dwarf Berserker, wondering if taking Superpower prodigy at level 30 is worth it. What does "+30% willpower modifier" mean?
