Is it possible to use a swift or immediate action between attacks? The language indicates clearly that a swift action can occur during a round in which a character takes a full round action (such as a full attack), and that a swift action may be used at any time at which a character could use a free action. Furthermore, free actions can be used "while taking another action normally." The only stated limit on free actions are those imposed by the GM. So, I posit the following situation:
A polearm master fighter archetype is equipped with a reach polearm. He is surrounded by enemies, and each of those enemies has another behind them, waiting to get into range. He has whirlwind attack and the "pole fighting" class ability, which states:
"Pole Fighting (Ex)
At 2nd level, as an immediate action, a polearm master can shorten the grip on his spear or polearm with reach and use it against adjacent targets. This action results in a –4 penalty on attack rolls with that weapon until he spends another immediate action to return to the normal grip. The penalty is reduced by –1 for every four levels beyond 2nd.
This ability replaces Bravery."
Is the fighter allowed to use whirlwind attack to attack all enemies near him (assuming he already choked up on the weapon), then use an immediate action to return his grip to normal, then continue to make whirlwind attacks against all of the foes who are now in the reach of his weapon?
I did this build in a mid-level game once, and the GM was fine with it, but I'm curious if it was actually as legit as I thought at the time.
