Alchemist's Shock

Alchemist’s spark combines two substances that react violently when mixed. A flask of alchemist’s spark has two compartments that keep the two substances separate; throwing the flask shatters it and allows the substances to mix, releasing a powerful electrical discharge. Otherwise, alchemist’s spark functions like alchemist’s fire except that it deals 1d4 points of lightning damage on a direct hit, rather than fire damage. It deals no additional damage after the initial damage. In addition the affected creature's limb become numb, slowing their reaction time, losing their reaction. The creature must then make a DC10 Constitution check to overcome the numbing affect.
