1: I'm probably going to increase the AC bonus, but not by much (+1/3 bending levels). It is meant to replace your armor though, so it's definitely not going to stack. As for concentration, I did mean to add an augment to make it a free action maintain, but it's definitely not going to be a +1 or 2 (those are reserved for tiny bonuses, like +1 to a skill or something). it'll be about a +8. That makes it so you won't be able to reliably do it until level 6 or so. And I don't know why it's a move action concentration right now, it should be swift. I thought I changed that. I didn't even notice it until right now. It did used to be more powerful (justifying the move action concentration, restricting you to bending as a combat means, and no movement), but right now it's intended to act as an alternative to armor, and it should end up slightly more powerful, but in a different way, than regular armor. Would you recommend going back to the powerful, deserving the move action concentration, or acting as an armor replacement?
3: It scales MUCH faster than that. it scales at 1d6/4 points, which is about 1/2 levels (probably slightly faster), as you gain +1 point per level, +1 point every time your wis bonus increases, and +2 points at 3 and every 4 levels past that. And then you can increase it further with feats, although that won't be much. There is also the successful save still having a penalty, although it's not a big penalty. i really should add -2 to attacks for that (non-stacking, of course).
10: ah, yeah, that's a problem. The line is supposed to be that: a line. The cone is supposed to deal more damage, and I did say I was going to switch them. Good eyes.
