So, for the Gunslinger class, which I admit has made me stoked, I realised that there is this nifty little combination of feets and deeds that could make it rather... painful against nearly everything.
The first question I have is this: How do you gain more attacks with the gunslinger when it comes to using two or more pistols? There was a mention of the Two Weapon Fighting feat somewhere in the UC, but I can't find it now, so how does rapid shot work?
The reason for this is that I want to know the maximum number of possible attacks per round, disregarding the need to reload, as this affects the Deadshot Deed.
Assuming a BAB of
+16/+11/+6/+1
this would give
+14/+14/+9/+9/+4/+4/-1
with Greater Two-Weapon Fighting. Adding Rapid Shot, if possible, would make this
+12/+12/+12/+7/+7/+2/+2/-3
of potential[/d] attacks that can be done as long as the Gunslinger uses twin pepper boxes or could just draw and fire pistols until the number of attacks have been reached.
For the unknowing; Deadshot is a fullround action that costs 1 Grit Point and allows you to roll a number of attack rolls equal to the maximum number of potential fire arm attacks you could do in a round, need to reload ignored, and then for each attack roll that hits you add the amount of damage die you get from firing the weapon in the first place in a similar manner to Vital Strike.
When using this wielding two normal one-shot pistols, would the
+12/+12/+12/+7/+7/+2/+2/-3
still be the number of attack rolls for Deadshot?
Since this, to my knowledge, is only a single attack action (a fullround attack but still a single attack) would it not be possible to use Vital Strike with this as well? If yes, would vital strike simply add another set of damage die to the damage roll or would it add the total number of damage die given? The latter seems extremely overpowered, not something I would allow as a GM, but I want some input on it.
Considering the vs-touch-AC-within-first-range-increment property of nearly all firearms, the +6 to hit one is likely to get from Dexterity at that level, including the modifier for Point-Blank Shot, and the minimum +1 that both weapons would have at that level the final number of rolls would look something like
+21/+21/+21/+16/+16/+11/+11/+6.
Assuming a standard AC value of 31 for CR 16, and then that out of this the touch AC is roughly 21 the hit percentages would be
95/95/95/80/80/55/55/30
which on average means that at least 7 rolls good enough to hit.
The Double-Barrelled Pistol has the property that both barrels can be fired at once with a -4 penalty to hit but doubling the damage done, this would in Deadshot mean
+17/+17/+17/+12/+12/+7/+7/+2
or in percentage vs 21 touch AC be
85/85/85/60/60/35/35/10
an average of 5 successive attack rolls.
Damage wise, only by dice, this would in combination with Greater Vital Strike (according to the non-OP way) be a total of 49.5 damage (1d8+10d8) for single shot and 81 damage (2d8+16d8) for a double-shot, on average. This is before weapon properties like flaming, enhancement bonus, pistol training bonuses (pistolero archetype), Up Close and Deadly (pistolero archetype), etc, are added in.
If I am correct on Double-Shot then properties like flaming and enhancement bonus to damage would double as the projectile number doubles while pistol training (hitting where it hurts) and Up Close and Deadly Deed (the former, only better) would only be applied once.
so for funsies sake, assuming only one energy damage property on the +1 DB Pistol, we have a total of
1d8+1+1+8 +10d8+5d6 (Enhancement+PB Shot+Pistol Training +Deadshot+GV Strike+UC and Deadly+Flaming)
which averages at [b]77 damage in one shot.
2d8+2+1+8+6 +16d8+6d6 (Enhancement+PB Shot+Pistol Training+Devastating Strikes +Deadshot+GV Strike+UC and Deadly+Flaming)
which averages at 119 damage in one shot.
And this is not taking into account that Deadshot Critical Threatens should even one attack roll result in a crit (but you confirm it with your highest BAB-5, decreasing the penalty by 1 per additional critical threat you get).
So yes, some help here, is this even viable?
P.S. I assume the double-shot to send the bullets close enough together that the damage is added together prior to applying DR.
