I agree that they should have more than healing and support, possibly non-lethal moves to avoid being killed and to fight back though, like illusions, going invisible, turning people around or somehow getting rid of them/stopping them from fighting in some other way. Orb already goes into some of this, with nausea.
I quite like orb the way it is currently tbh, it's a very unique ability since it can be placed,
though admittedly i hate being hit by it xD
Just mentioned it as a way to show that non-violent moves are already part of the spirit playstyle.
