Killer distortion type perk idea

A rough perk idea for the killer that would prevent aura reading based on a token system. At first, the killer starts with, let's say, 3 tokens. Each time the killer's aura would be revealed, instead, a token is consumed, and their aura is not shown. Additionally, the survivor would scream out, interrupting any action, and maybe to make it more interesting, prevent item use for 15 seconds. I'd say the perk should only be able to be triggered every 45 seconds.

Additionally, you gain one token each time a survivor blinds you or when you hook a survivor (The blinding is to keep the perk based around items and a kind of increasing sense of maliciousness). The cap would be may 4 or 5 tokens.
