The funny thing is that if I pick Steel Serpent as one of my disciplines known, I'd need to take ranks in Heal. What better doctor than someone whose hands are blood-drinking scalpels?
As far as picking disciplines, Falling Star is right out. I like Coin's Edge, Oncoming Storm, Scarlet Rose, and Steel Serpent, but they all take skills (Profession (gambler), Sleight of Hand, Perform (dance), and Heal) that either involve fine manipulation or are otherwise less useful. Hrm.
