So I was reading the Stealth skill and came across this part:
If people are observing you using any of their senses (but typically sight), you can't use Stealth. Against most creatures, finding cover or concealment allows you to use Stealth. If your observers are momentarily distracted (such as by a Bluff check), you can attempt to use Stealth. While the others turn their attention from you, you can attempt a Stealth check if you can get to an unobserved place of some kind. This check, however, is made at a –10 penalty because you have to move fast.
Creating a Diversion to Hide: You can use Bluff to allow you to use Stealth. A successful Bluff check can give you the momentary diversion you need to attempt a Stealth check while people are aware of you.
And I know that it's been ruled that the Blur spell's concealment is enough to allow you to use Stealth.
Looking at the Bluff skill description, it says nothing about this at all. It does mention Lying, Secret Messages, and Feinting, and describes what kind of action they each are.
So, from what I can gather from the rules, it looks like you have the ability to perform a full attack while "stealth cycling" to continuously make your opponent flat footed to you by distracting them and quickly hiding again after every attack. Sort of like using your magical concealment and fighting style to continuously slip under the guard of whatever creature you're fighting because they can't really tell where your weapons are coming from.
By attacking, bluffing successfully, stealthing successfully with a -10 to your stealth roll, attacking, bluffing successfully, stealthing successfully with a -10 to your stealth roll, and etc., until you run out of attacks, you can sneak attack on every attack if you have that ability.
Bluffing this way uses no action, and neither does stealth, since you don't have to move to get back into concealment.
Best of all, you can end the round in stealth by bluffing and stealthing once your attacks are done. One 5 ft step later and they no longer even know which square you're in.
