If you're unarmed, you don't threaten, and neither you nor your ally get the flanking bonus. Both must threaten for it to work.billd91 said:Technically, I don't believe this is true. You can make a melee attack unarmed without improved unarmed feats and not threaten. This is, I believe, one instance in which flanking is not reciprocal between flankers. You might get the flanking bonus if you attack with your fists, but your flanking partner might not flank because you are unarmed and don't threaten.
EDIT: Obviously, the Improved Unarmed Strike feat causes you to threaten, in which case you and your ally get the bonus.
There isn't, to my knowledge, a situation where one person qualifies for the flanking bonus and the other doesn't.
