[Suzerain of Sheol]

I think my original idea was that they'd be used in mounted or crew-operated weaponry, and that to use them on a man-portable firearm would require an extremely specialized design, and almost certainly end up being less effective than the weapons they were designed to be fired out of.

Though, I suppose we could have a scaled down version of the same round that can fit into conventional weapons, just bearing in mind that "effective" in that case means that "it makes the Balrog notice when you empty a clip of them into him" not "gibs the Balrog". :p

(they were primarily designed to wound greater demons)

But, anyway, we DO have an artificer in our party let's remember.
