Well i play with a 5 mage 1 cleric aprty but that is not the best
lemme see
Paladin (pref. Inquisitor but all kits are great)
Ranger/Cleric (dualled from ranger to cleric you'll get all the spells)
Sorcerer (give him/her a change and he/she will turn out to be GREAT)
specialist mage (Conjurer or Necromancer to give you more spells)
Kensai/Mage (ever special dual combo) (Accord likes bezerker mages more)
Fighter/Assassin (dualled from Fighter not a legit Class - Assassin benefits most from leveling up)
You have three mages my robe suggestion is
Kensai/Mage - Robe of Apprenti
Sorcerer - Robe of Good/Neutral Arch magi + amulet of power
Specialist mage - Vacna's Robe
