Yes, as per Player's Handbook FAQ
Found reference here:
Attack powers that have a target line and deal damage are attacks (See: Magic Missile). Ergo, Flurry of Blows is an attack.
This is clarified in the FAQ for Player's Handbook, in case anyone was wondering where it's coming from.
And the relevant original text is here (item 38):
- What happens if I use magic missile while benefiting from a power like greater invisibility? Does it count as an attack and would my invisibility end?
Yes, it does, and yes, it would. The initial use of any attack power that has a target line, an attack line, or both counts as making an attack. Because of this fact, using an attack power like the fighter's rain of steel does not count as making an attack, since the power has neither a target line nor an attack line
A Full Attack option is (usually) compromised of several attack rolls, or individual attacks, which takes the entire round (6 seconds) to complete. As noted in the description of a Full Attack (emphasis mine):
If you get more than one attack per round because your base attack bonus is high enough (see Base Attack Bonus in Classes), because you fight with two weapons or a double weapon, or for some special reason, you must use a full-round action to get your additional attacks.
This means that the "Before the attack" refers to the attack roll which you want to use Flying Kick with. So, yes. Starting Flurry of Blows with attacking A with one attack, then using Flying Kick to move to and attack B with the next attack, is what this ability does.
The Fast Movement Bonus is the bonus to your speed, as listed in the Monk level table. Meaning at third level you can move up to 10 feet, when using Flying Kick.
The reason why it specifies that this attack must be a kick, is for two reasons:
- It's called "Flying Kick", as in the actual martial arts move's popular name.
- To prevent it from being abused to attack with a weapon instead.
As for the movement bit being broken up. It states that the monk can move up to that distance. Meaning if you move only some of the Fast Movement bonus distance, you won't get the rest as "extra movement" later on.
Effectively the movement stops when you hit something, as in real life. ;)
Lastly, the multiple attacks bit. From the description of Style Strikes (emphasis mine, again):
.. he can designate one of his unarmed strikes as a style strike. This attack is resolved as normal, but it has an additional effect depending on the type of strike chosen. At 9th level, and every 4 levels thereafter, a monk learns an additional style strike. He must choose which style strike to apply before the attack roll is made. At 15th level, he can designate up to two of his unarmed strikes each round as a style strike, and each one can be a different type.
So only at level 15 can you use Flying Kick twice in a round, but you can move up to the full distance for both of them.
Best Answer
There are conditions that prevent characters from taking actions altogether (stunned, unconscious, dying, etc). This prevents free actions, but a "No Action" power could still be used. Also note that most powers that enhance your initiative are No Action because you are using them before combat technically begins.
For example, a Deva could use the Memory of a Thousand Lifetimes power to boost a saving throw taken while stunned, but a Battlemind couldn't use Battle Resilience while stunned.
My guess at the reason this particular power is a No Action power is that you can normally only make one attack as a free action per turn. "No Action" powers don't count toward this limit.
Centered Flurry of Blows could be argued to be an attack power, and thus use up your 1 free action attack per turn. Giving it a "No Action" ensures that it doesn't.
