secret obsession offering ideas

in my eyes it is to easy to see the secret offerings becouse for surviver you only have shrouds and for killer you have 1 shroud (that no one uses) or mori's so I have some ideas for extra offerings

both killer and surviver
  • there is a obsession (this can throw the other off that there is an obsession perk)
surviver
  • you chances increases to become the obsession (slightly, moderately)
  • you are will not become the obsession at the start of the game
  • you will become the obsession at the start of the game (even with no obsession perks)
killer
  • there is no obsession at the start of the game (to disable some perks like object)
  • the first surviver hit will become the obsession (to choose your obsession)
  • the obsession will be spawned closest to you
