For your bard maybe one of the saving throw ones, whichever you're worst at. Same for cleric. Luck of heroes IMHO is a waste. I would say either sf evocation or gsf enchantment, depending on how many evocation spells you cast. For your fighter/etc not dodge, AC's not that important. Maybe one of the saving throw ones if you need it. I never got slippery mind, so I dunno - probably if your saving throws were high enough you wouldn't need it? I would get improved initiative (for all actually). For your mage I would definitely get scion of storms. Yes the only useful lightning spell is chain lightning but this IMO is the best offensive spell in the game - hits lots of enemies and doesn't hit you. Does lots of damage too with sf evocation and scion of storms.
