Necro: A gnome that has forsaken his race's tradition (it is not a trait per se right) to become an illusionist and joined 'the dark side' of necromancy.
Ogre: Stupid and cunning, but not as kind as Minsc. Perhaps a shaman type. I know he is a goblin, but the one that lead the attack on Targos, Caballus IIRC, had this excellent dancing animation.
My 2 cents anyway
