Your nearly supernatural mental connection with your allies keeps you in a constant state of readiness.
Benefit(s): Whenever you’re adjacent to an ally who also has this feat, if your ally is not flat-footed, you’re also not considered flat-footed before you act in combat (you might become flat-footed in other ways, however).
Additionally, if your ally can see a creature that you can’t see, that creature doesn’t gain a +2 bonus on attack rolls against you from being invisible, nor do you take a –2 penalty to AC for being blinded if your ally can see.
