Pipe Knuckles

These brass knuckles have a built in magic pipe!
The pipe has 12 charges and can be recharged
with the right juice. One charge produces a fog
that covers a 5x5ft radius. The cloud smells and
tastes like pineapple.
Charges can all be used at once. Be careful,
though, using too many at once may make
you sick!
Melee damage with this weapon does 1d4+2.
