Dead by Daylight

you will just unlock this naturally if you play nemesis alot

but if you want this faster just prioritize his whip than his default attack, use his whip when survivors are in a animation lock (I.E vaulting over a pallet or window) but survivors in some windows could crouch and hide behind the window vault so be weary of that, the whips hitbox can be strafed (I.E you can move the hitbox during the animation by moving the camera mid animation) use this to your advantage if youre by a corner release the animation early and then drag the camera, even with this tip the hitbox still can be janky even when you think you had a clear line of sight and whip the survivor at an angle the hitbox could hit a wall or something and canceling the entire hit keep that in mind

Map: Midwich
Addons: Serotonin Injector (15 secs of Undetectable when a zombie dies by any means) and NE-a Parasite (60s on Oblivious on a Survivor once they become contaminated, can be stopped early by a syringe).
Perks: Hex: Plaything (survivors hooked for the first time will have a Hex lit and linked to them, making them Oblivious until it's cleansed), Hex: Face The Darkness (Injuring a Survivor activates it, once activated survivors outside your terror radius ((being Oblivious counts as being outside of it)) scream and get interrupted every 25 seconds), Hex: Pentimento (destroyed totems highlighted in white can be reignited for various detrimental effects, like slower heals and gen repair) and Save the Best for Last (50% weapon wipe speed for each token, lose 2 when hitting the obsession).

Basically, what got me the most results was a sneaky Nemesis build that allowed me to get the drop on the survivors. Midwich was the perfect map for it due to its close quarters and narrow hallways.
Bait out pallet drops and window vaults as best you can, and funnel them within the hallways.
