I have a Henry!Brady that went through theif-->assassin and he's great, but I don't know which way he should go next...

I want to make him part healer, so either Trickster, War Monk, or Sage but I can't decide which.  Anything but sorcerer, I have too many of those.  Any suggestions?

Right now his skill set is: Galeforce, Lifetaker, Lethality, Locktouch, Movement +1.
