Psychic Chatter, Shrieking

Biotech

Brain matter from a corrovox (Alien Archive 110) implanted into your own mind emits a constant psychic background noise in your head. You eventually become inured to the effect and can concentrate normally, although you’re prone to headaches. You can focus this psychic noise into a damaging burst of mental static that emanates from you. If an opponent within 5 feet hits you with an attack, you can use your reaction to deal 8d4 damage to that attacker. If your opponent’s attack roll is a natural 20, the attacker also gains the shaken condition for 1 round. This is a mind-affecting effect.
