# calculating damage for double-barrel guns

### Rules Questions

Say I'm using a double-barrel pistol, and I have +10/+5 to my attacks. Do I roll attacks twice, and if they both hit, I roll damage 4 times?

Trick is you'd need to reload the pistol between firing. I'm not aware of any method that will let you reload both barrels partway through a full-attack. If you somehow are able to do this, the you'd roll for attack four times (twice at the +10 and twice at the +5 increments) and roll damage for each hit.

Yes, but do remember that free actions can be limited to what your DM feels is reasonable. Yours may not feel that reloading two barrels is a reasonable amount of free actions to get in the middle of a full attack routine.

Also, don't forget that you're getting a -4 to each attack for firing both barrels at the same time. So +6/+6/+1/+1

Given the hefty -4 penalty, along with having to burn a feat and use a special type of cartridge that I'd end up crafting on my own, I'm fairly certain my DM would allow it. People with crossbows can take Rapid Reload to make a move action become a free action, and they can do it all day long without a DM batting an eye.

In any case, thanks for the answer. For some reason I thought that a double-barrel would use one attack, so that if that one hits, then they both hit, but if it misses, they both miss, but good to know that's not the case.

So if I was using Haste, would I end up with +7/+7/+7/+2/+2, or would it be +7/+7/+7/+7/+2/+2?

EDIT: Added the +1 from Haste bonus.

Yes that's correct. At that point I hope you have a means to either prevent or quickly clear jams; with so many attack rolls the odds of a bad roll are getting pretty high.

Actually, misfires can be quite nasty with double-barreled (early, not advanced) firearms. Because firing both barrels is part of the same action, if both barrels misfire the first misfire causes the firearm to gain the broken condition and the second misfire (more likely now because of the broken penalties) causes it to explode. Quick Clear won't help since it requires a separate (standard or move) action but Stranger's Fortune might if your GM lets you take a free action simultaneously with the attack action.

I disagree. A gun only explodes when it misfires while it has the broken condition. Since both barrels of a double barrel weapon fire simultaneously then the misfires occur simultaneously and thus the gun does not actually have the broken condition at the point that either misfire occurs. Ergo it would simply count as a single misfire. Alternately, I have seen some DMs essentially treat each barrel as a seperate weapon regarding misfires, though that isn't strictly RAW. RAI-wise I can't see the designers expecting someone to schill out 2,000+ gp on a weapon that catastrophically destroys itself 1-2.25% of the time you use it.

A review of forum topics shows most people agreeing with you, trollbill. Two misfires when firing both barrels on one attack only gives the broken condition once but for the entire weapon.

The downside to the double-barreled firearm is you do end up with two chances to misfire on one attack but it's not as catastrophic as I originally thought.

I'll take the misfire chance.

Still need to know:
if I was using Haste, would I end up with +7/+7/+7/+2/+2, or would it be +7/+7/+7/+7/+2/+2?

Most DM's would rule it +7/+7/+7/+7/+2/+2. However, there is a catch with the double barrel pistol. The wording for the double barrel musket and shotgun says you can fire both barrels a part of the same attack. The wording for the double barrel pistol says you can fire both barrels as part of the same action. Now this could just be a typo/poor word choice on the part of the designers or it could have been deliberate. Unfortunately, if it was deliberate this puts the weapon in a similar grey area as Vital Strike regarding the definition of action. It could mean all attacks, it could mean only for one attack per routine or it could mean it can only be done as part of a standard action attack. The confusing nature of the wording is why most DMs tend to let it work like the other double barrel weapons but it is subject to interpretation.

Like trollbill says it's +7/+7/+7/+7/+2/+2. It basically doubles all attacks at a -4 penalty. Don't try to two-weapon fight with them or your DM will give you a swift kick in the rear.

Lol, nah, no twf for me. I can't imagine the reload action with twf in my head. Seems too silly for me.
