Hellfire Sparkler (Price 250 gp; Weight 50 lbs.)
This large barrel-shaped sparkler is imbued with mysterious, hellish forces. The fuse can be lit as a standard action; 1d4 rounds later, the sparkler crackles violently with sickly-green sparks that take the form of an army of ferocious devils. Creatures within a 10-foot-radius burst take 3d6 points of fire damage and become shaken for 2 rounds; a target can attempt a DC 15 Will save to halve the damage and the duration of the shaken condition.

Crafting a hellfire sparkler requires a successful DC 25 Craft (alchemy) check.
