Ah, sorry I missed this.
Skills you should get *in order of usefulness*
Increase HP Recovery
Increase SP Recovery
The various other blows
For Knight Skills:
Defense Encouragement is...ok. Not exactly gonna be used all the time.
Big Fighting Spirit is the same, by that level you'll be grinding with people that can res anyway and stuff.
Pledge, Sacrifice, stuff you use when you can't find a vates.
Spear Intercept sucks, quickly gets unused once you get Divine Spear and start raping Hell Divers.
