I just made a bunch of sets of gnomish fireworks...The recipe is
Firewater (1)
Bat Wing (1)
Metal Shaft (1).

This costs around a gold to make and produces 4 separate fireworks.
They differ in that each one has a different effect (Fireworks1,
Fireworks2, Fireworks3, Fireworks4). Unfortunately the effect of each
one is horrible! They might be broken, but as of right now they do
nothing but send a TINY colored flame straight out from your body and
lasts about a tenth of a second at best. The difference between the 4
types seems to be color of the flame. That is IF you even catch a
glimpse of the flame (if you blink you will miss it). About the only
good thing I can say about them is that Im glad they cost me next to
nothing to make, since for now they seem to be a complete waste.

I hope this was an isolated experience and that other people have more
luck than I do with them.
