They have Master (War of the Lance, pages 21-25), Noble (Dragonlance Campaign Setting, pages 50-52), Mystic (Dragonlance Campaign Setting, pages 47-50), Nightstalker (Races of Ansalon, pages 153-156) base class that I have my eyes on. And Healing Hand of Mishakal (Holy Orders of the Stars, pages 42-43) and Warmage (Age of Mortals, pages 48-49) prestige classes.
I am looking to play either a healer, blaster or support classes in case I lose interest in my primary choices. The prestige classes are to boost healing and blasting.
