If I use the Rogue Talent False Attacker with Hide in Plain Sight would I get sneak attack on all my attacks if I use a full attack action and make the bluff checks?
False Attacker (Ex)
Benefit(s): Whenever the rogue strikes a foe from hiding, she can attempt a Bluff check as an immediate action (opposed by the target's Sense Motive or Perception check, whichever has a higher bonus) before rolling damage to convince the foe that another creature was the attacker. This Bluff check applies the normal modifiers for convincing a creature of a falsehood, but can be accomplished with just physical trickery (a shared language is not required). If the Bluff is successful, and the rogue maintains concealment or cover, the rogue's stealth does not end.
HIPS lets you stealth without cover or while observed, gaining total concealment.
The stealth skill says "It's impossible to use Stealth while attacking" and "Your Stealth immediately ends after you make an attack roll, whether or not the attack is successful (except when sniping as noted below)."
It's unclear to me, but it seems as if False Attacker functions only on a hit because it mentions "strikes" rather than "attacks" and talks about rolling damage.
It's also unclear to me if it can function for more than one attack, due to the use of an immediate action to make the bluff check.
It seems that a successful bluff alone is insufficient to maintain concealment or cover and neither is HIPS. It would have to be some other sort of concealment (such as an attacker with darkvision attacking in darkness against a foe without or with fogcutter classes in a fogcloud).
Kind of? You only have one immediate action, so you can make one attack, bluff, and then another attack and end your turn unhidden.
Just reread the talent, and noticed the immediate action. Too bad, could have been a fun build.
Where is that talent?
