@Gothix Hmm, sounds pretty occult . Too bad there is so few gods and only one is "evil" and none is specialised in anything (all of them somewhat generalised as "god of magic" or "god of beastmen"... in ADaD every deity had at least favourite weapon - could be doable here too, just give some kind of bonus with flavour of deity - and some spells only gods could teach you. Not necesarilly gods, I´d worship any lesser demon, if he granted me some kind of deeper specialisation ).
Would also be nice to have some casting offhand ... preferably heads of monsters from which you learnt some spell, so these would give you bonus to spell you learnt from them (example: stronger fireball, if you kept shrunken head of goblin shaman
