Decisive is amazing with STBFL
Tunnel someone on death hook when you have lots of stack of STBFL. If they have Decisive Strike, they become the Obsession and you only lose two stacks to kill them and keep six stacks for the rest of the game.
Moral of the story is that tunneling and getting "punished" with STBFL is amazingly good.

If someone else becomes the obsession wouldn't that reactivate the perks ability to gain/lose tokens?
I think so. Taking another DS hit, or a stun while running Oni's Nemesis perk, would do exactly that I believe.
