Some Killer Perk Ideas

Boss

Persistance

Persistance starts with 3 Tokens.
Breaking a Pallet while chasing a Survivor consumes 1 Token.
As long as Persistance has at least 1 Token, breaking Pallets doesn't remove Bloodlust Tier 1 / 2 / 3 and lower.
Successfully putting a Survivor into the Dying Health State restores all Tokens to Persistance.

Denial

Allows you to re-close opened Exit Gates by flipping the Exit Gate Switch for 5 / 4 / 3 seconds.

Rampage

Once per match, you may damage a Generator that's fully repaired, making it have to be repaired again.
The damaged Generator's progress will regress 10% / 18% / 25% faster than usual.
After damaging the Generator, it will also gain Entity Blockers for 10 seconds, blocking any Survivor from touching it while they're up.
When all Generators are repaired, Rampage is disabled.

Very interesting! Some don’t seem too OP, but they do seem good. I’d like the killer to hit the switch with their main weapon, because if you see the Hag openly pull the lever [WRONG LEVEEEERR] it wouldn’t look right
