i think every killer should have 2 ultra- rare addons

This is only a opinion btw. Im just naming some ideas that i have for killers that have only 1 or no addons

Doctor:
Spine coil: A large energy coil, used to torment his patitents by hand, attached to the Doctors spine which gives him following affections. The Doctors shock therepy now goes out from all around him in standard range and increases madness inflicted by 25%

Hillbilly:
Toxic fuel: The Hillbilly's most succesful fuel for his chainsaw, used to slowly cook the lungs of his victims. While the chainsaw is active, all survivors within the terror radius suffer from the exhausted status effect
Heart beat sensor: A oldschool heart beat sensor that was used by the Hillbilly's dying grandmother whos survival will not be forgotten. survivors hear a heart beat from all over the map the more the chainsaw is charged and while chainsaw sprinting the heart beat is gonna be like Hillbilly was right behind them

Nurse:
Mary's curse: The nurse always keeps this to herself, no one know what it is and where it came from, people call it a curse and she calls it a blessing. the Nurse can now freely move around while blinking

these are just ideas so far
