Hook the Obsession 10 times
So I found a really good combo where you can get this done in 1 game if everything goes well.
2 Perks required: Nemesis, Furtive Chase.
If you find the obsession first. Awesome! Get them down and hook them. Now your obsession is on the hook. 2 things can happen. If you find someone else you can force them to pallet stun you by lunging in for a hit and making them drop the pallet and now you have a new obsession from NEMESIS to hook.
Or! If you don’t find anyone in time and someone saves the obsession from the hook they rescuer is now the obsession because of FURTIVE CHASE, which is great because now you have a new obsession to hook without even doing anything. But wait there is more! Since you have NEMESIS the new obsession that got switched because of FURTIVE CHASE now is oblivious 60 seconds and you see their aura for 4 seconds. So if you couldn’t find anyone else you can go to the hook and see where they are headed and cut them off for another easy obsession hook.
Note: FURTIVE CHASE only gives you a new obsession IF the CURRENT obsession is on the hook. So if you were mid chase and got stunned and got a new obsession and someone else gets the save a few seconds after it’s okay because you are still chasing your obsession.
