Hey BHVR here are some good perk concepts
As we all know killer perks have been terrible lately. Last good one was thrilling even though bbq is probably better. Surge has potential but the range and regression need to increase. Also surged gens should regress at 150% rate. BHVR you have this mechanic so use it.
Anyway here are some perks you could use
After landing any 2 hits the perk activates. The next time you kick a generator it will regress at a 200% rate and all generators within 64m will regress at a normal rate.
When survivors repair a generator all generators not being worked on will be blocked for 45 seconds.
Downing a survivor causes all healthy survivors outside of your terror radius to become injured and all injured survivors get the deep wound status. This has a cooldown of 60 seconds.
Hex: 2 generators are randomly selected at the start of the trial. These generators are blocked until the hex is cleansed. Yes it stacks with corrupt so 5 gens will be blocked but this hex can be cleansed fast and corrupt only lasts 2 minutes.
After hooking a survivor you move 25% faster while outside of a chase for 60 seconds. This resets if you get another hook.
After breaking 3 pallets the perk activates. The killer can destroy a pallet than hasn't been used yet.
Hitting a survivor causes them to become broken for 60 seconds. This has a cooldown of 40 seconds.
Let me know if any of these sound good.
