I was actually in the process of deleting that last comment I made before I got ninja'd. Oh well! The replacement follows:
I'm thinking I might take Hands Afire after all, to help boost damage where I can, or if I need to set something on fire... >_> <_<
So that would make: Circle Kick (attack/hit two adjacent foes), Deadly Reach (attack at 20' reach), Hand Afire (+1d6 fire damage on hit), and Leg Sweep or Scorpion Claw (Free Trip or Grapple attempt on hit). Alternatively, I considered Three Sided Strike (treat enemy as being flanked) in case I need a bit more chance of hitting...
I'm also left with one free feat, so that's a consideration right now as well. Weapon Finesse + Combat Martial Arts are both required, but the third feat from being Human isn't yet spoken-for.
Garryl: Thanks for pointing that out. I may pick up a light shield or buckler, then.
What I typically do for armor special abilities on armorless characters is use Gnome Twist cloth. The ACP of 0 similarly doesn't impact non-proficient classes, and the +1 armor bonus either helps someone without armor a tiny bit or is cancelled out by a better armor bonus; but you still get to benefit from any armor special abilities. There may be better options but it works pretty well for me.
As for the Numens, Brilliant Dawn is useful if most of the party has no way to see in the dark aside from lighting torches/campfires, and the bonus to attacks is useful. Unseen Impetus can help with AC and granting a weapon ability we'd otherwise have to buy. Eternal Moment is a fun circle anyway, plus bonus to initiative is always appreciated.
Any of them would be useful to some extent or another, though I think those are the top 3 for me.
