Synaptic Static
Synaptic static interferes with all psionic activity within a given area. Even the psionicist is affected; when he create static he cannot use any other power simultaneously. However, he may also prevent others from using their powers. Anyone who tries to use a psionic power within the area of effect must fight the static's creator in a psychic contest.
If an opponent succeeds, his power functions normally. If not, his power fails. Exposure to synaptic static for more than five rounds will give anyone a splitting headache. This has no game effect but it will make NPCs and animals irritable. This power has three ranges: short, medium, and long. At medium range, the character's power score is reduced by two. At long range, it is reduced by five.
