Alchemist's Fire

Effect: Thrown as a splash weapon (10 ft range increment).
A direct hit deals 1d6 fire damage; creatures within
5 feet take 1 fire splash damage.

The next round, the target takes 1d6 fire damage.
They can use a full-round action to attempt a
DC 15 Reflex save (+2 if rolling on the ground)
to extinguish the flames. Leaping into water or
using magic extinguishes the flames automatically.
