If an Envoy uses Clever Attack with a ranged weapon while threatened, does he provoke? Does an ally using a ranged attack against a clever feinted foe provoke? I don't think it does, because flat-footed prohibits reactions (so it would provoke but the for couldn't do anything) but I'm not sure if I'm missing something or if this is against the intent.
Relevant text from SRD:
As a standard action, you can make a single attack against a target within 60 feet and gain the benefits of clever feint (attempting a Bluff check against the target as normal). Apply the effects of clever feint before resolving your attack.
As a standard action, you can fake out an enemy within 60 feet, making that enemy open to your attacks. Attempt a Bluff check with the same DC as a check to feint against that enemy (though this isn’t a standard check to feint, so Improved Feint and Greater Feint don’t apply). Even if you fail, that enemy is flat-footed against your attacks until the end of your next turn. If you succeed, the enemy is also flat-footed against your allies’ attacks until the end of your next turn.
At the start of a combat, if you are surprised, you are flat-footed until you become aware of combat and have had a chance to act. Many other effects can cause you to become flat-footed. You take a –2 penalty to your AC and cannot take reactions while flat-footed.
