Alright, I've got an idea for several feats, which will eventually be leading up to a bigger feat, of which the other feats are pre-requisites in SRD.
This one is one of the toughest. In SRD, you select a -single- target, and get a +1 dodge bonus to AC. Mechanically speaking, in FK, that would be difficult. Also, we already have a dodge skill, which I believe I've read does much the same, but without the single target limitation (though the help file doesn't reflect that.. maybe an update is in order?).
Not all classes get the dodge skill, but as a feat, this would be theoretically available to anyone who meets the pre-req (13 dex). Perhaps someone with this feat would get a +1 ac bonus against the mobile they're actively targeting?
