Pathfinder Society Adventures
When lit, this foot-long wooden tube begins to shake and emit a handful of white sparks, shedding light as a torch. One round later it takes flight, moving in a straight line with a fly speed of 90 for 1d6 rounds before loudly exploding in a burst of light and sound, dealing 2d6 points of fire damage in a 10-foot burst [DC 15 Reflex save for half]. If a skyrocket impacts a solid surface or a creature before reaching its maximum range, it detonates prematurely at the point of impact. Anyone who takes damage from the explosion is either blinded or deafened [a 50% chance of either] for 1 round.
Cost: 50 gp
Found on a wrecked Chelish ship called Kajitsu Star in the Brinestump Marsh in Varisia.
