So, I finally got the 3.5 version, and I did not see ki Channel. So I was wondering if I just missed it, or it wasn't put in 3.5 because it either, a) was too broken to be able to use Flurry of Blows with a weapon, b) was just to similar to ki Focus, or c) because you can use Flurry of Blows with any weapon a monk is proficient with as a Dungeon Master once told me.
Also, where Jagged says it doesn't stack with Keen how does that come into effect, because the way I see it, Keen and Jagged aren't applicable to the same stat... So, does it just mean you can't have it on a weapon that already has Keen, or if you have a weapon that has both, you have to chose which one will be applied to any given attack?
I don't remember why ki Channel wasn't included but I would guess that it is too similar to ki Focus. As for Jagged, looking at the errata I don't see why it wouldn't stack. That will likely be one of the changes we make in the upcoming Pathfinder version of A&A.
