The gunslinger in our party has used the following tactic repeatedly since our DM allows it but I would like your opinion regarding the legality of it.
The gunslinger has the Deft Shootist feat allowing him to reload and fire his musket without provoking attacks of opportunity.
He hasn't got the rapid reload feat yet so whenever he wants to use his iterative attacks he moves in melee with acrobatics while declaring dodge to his target and at the next turn he attacks with the warhammer part of his musket-warhammer and at the last iterative attack (lowest attack bonus) he fires at his target, in a few words he makes two melee attacks and one ranged touch attack at every full attack while in melee range.
I assume he's spending a full-round action reloading the gun every second round and only doing the attack routine on the other rounds? Also, does he have a BAB of 11 or higher, or how is he getting three attacks in a round?
Also in PF you don't actually declare dodge to a specific target anymore, the dodge bonus to AC is just active all the time.
And unless he'a actually passing through at least one threatened square he doesn't need acrobatics (moving into a threatened square does not cause AoO, leaving it does)
But yes, what he does sounds legal. Just don't forget that he's usuing his 3rd iterative there, so he's at BAB-10 even if it's against touch attack there.
Why is he declaring his dodge? It doesn't work like that anymore, it's just +1 Dodge to AC.
Does it say anywhere in the firearm rules that you can't shoot the firearm in the same round as you melee with it? I assume it's no different from stabbing a couple of times with a dagger, then throwing it for your last attack.
I'm surprised he has the Str to make it work though, and the feats to get Deft Shootist but not Rapid Reload. Rapid Reload is like, the #1 first pick for gunslingers usually. I probably would've used the Musket Master archetype, if I was him.
