Weighted weapon + Lead Blades / Impact enchant = Will it work?

[DraGonKniGht20]

So this came up recently with my group that I normally game with. There's a bit of an argument going on but what it boils down to is, Would the effects of a crafted weighted weapon, and the enchant Impact/ spell Lead Blades, stack?

We're leaning towards no, following the same kind of ruling with Keen and Improved Critical.

Since we have no official, or other concrete proof on the matter, I figured I'd hop on here and give the question a go to be disected and discussed by the paizo community.

"Weighted"?

Impact and Lead Blades don't stack for sure.

[CriticalQuit]

I'm pretty sure a weighted weapon would just count as a weapon that's a larger size category. In which case, it would technically stack, because it's just an oversized weapon with an enchantment.

[DraGonKniGht20]

It's from the Mercenaries Book I'm told, a 3rd party book. I suppose it works the same as 3.5's mercury treatment of a weapon (hollow tube along mass of the weapon with mercury that shifts as the weapon is swung, counting dmg as a size category larger)

[Cavall]

Ah. Well of its third party that's a different question all together.

[CriticalQuit]

Yeah, you can't really determine whether or not 3rd party stuff stacks, it'd be pure DM's call.

There's no such thing as RAW for rules that weren't written by paizo.

[Nefreet]

Ah. In that case I'll flag the OP to be moved over to the 3rd Party Forum.

I hear 3rd Party authors regularly visit there and answer questions.
