Magic Stone in a Firearm

[Pharmalade]

Say I've got a Svirfneblin gunslinger with that racial trait that gives it the ability to cast Magic Stone once per day. Say also that it wants to use those magic pebbles in a firearm. What happens?

Is it at all doable?

My assumption: Normal firearm damage plus damage from Magic Stone.

Also, if you load the three stones into a scatter weapon along with other munitions, what then?

so you wanna shove rocks in your gun instead of cast metal bullets and hope it doesn't misfire?

Old scattergun ammo was rocks. I see no real problem with this in concept. Just randomly pick 3 targets in the scattergun AoE and use the higher damage value (don't add them together).

Depends on the gun, I guess. If the magic rocks are small enough, I guess it could work for non-advanced firearms.

I'd only allow it for a scatter weapon like a blunderbuss, not a single shot.

joking aside, i'd probably allow too, but increase the misfire rate by 1 like some of the special alchemical ammunitions.

if used in a scattershot, i'd probably not allow it, i figure the magic would dissapate as the rocks broke in firing, or only have a 50% chance of having any extra effect on each of the targets since 1 to 3 of the rocks were actually the magic rocks.

Scattershot weapons don't use a single rock that breaks up when the weapon fires. They just use a bunch of rocks.

As a houserule, this is a possibility. But just like you can't shoot magic arrows out of a gun, you can't shoot Magic Stones out of one either.

If you build your ammo yourself you should be able to build some ammo with stone instead of lead as projectile. (as always GM's call)

After doing so it should be possible to enchant those stone bullets with magic stone.

To quote the SRD

"...so that they strike with great force when thrown or slung..."

RAW, they aren't being thrown or slung, therefore the effect isn't triggered. I know the spell pre-dates the existence of firearms, but... that's the black and white of it.

Damage is also cited to be a flat D6+1. Not "1 size larger" or anything odd like that. At a glance (unless there is a clarification I missed) it also replaces the damage dealt by the weapon as a base, not add to it as your hoping.

Gut feel is that the spell is designed to bring a sling in line with doing damage as per a shortbow. Firearms typically already exceed that. In the cases they don't, change the dmg to D6+1. Otherwise the spell basically does nothing.

Ultimately, it's a level 1 spell. Firearm damage, (with a touch attack) PLUS D6+1 is probably a bit excessive.
