Hairspray Flamethrower: A can of hair spray and a
lighter is all it takes to harness the power of projectile fire.
Attacks made with a hairspray flamethrower require a Dexterity
+ Athletics roll. The flame emitted from a hairspray
flamethrower has a range of one yard, is of Torch size (Damage
1) and burns with the intensity of a gasoline fire (+2 Damage
bonus). Thus, an attack with a hairspray flamethrower
will never inflict more than three points of damage. On an
exceptional success, combustible items on the victim will
catch fire, and, the following turn, he’ll begin taking one
point of lethal damage per turn until extinguished (see p.
180, the World of Darkness Rulebook). A full can of hairspray
holds enough flammable material to make 10 attacks.
For cans characters just find lying around, the Storyteller
should roll a die; the result is how many attacks worth of
fuel the can contains.
Alternately, the can could be made to explode by
punching a hole in it and applying a spark. This produces
an explosive with Blast Area 2 and Force 1(L). See p. 101
for more information on explosives.
