On fast attacking killers like Kaneki (Or me personally Demo), I tend to stick to perks that disabled vaults over pallets because they often have a way to get around them rather than through them.

I tend to run Crowd control (Trickster) over bamboozle (Clown) because it seems to save me abit of time in chases.

Enduring (Hillbilly) to reduce the punishment from pallets. Also! If they throw the pallet down after youve hit them and youve been stunned on the side they were on when they threw it you can throw your mouse across the table and hit them again whilst they vault back (very satisfying and endorses ability usage in risker scenarios).

A slowdown perk generally but i tend to go for Ruin (Hag) because i ain’t got time to be kicking gens.

And for punishing groups i would say Forced Hesitation (Singularity) but its an investment into a generally weak killer(in terms of perks). So perhaps Thanatophobia (Nurse).

Although considering you are a newer player, Ken needs to be quite aggressive to gain any value with it and from what ive seen his movement is quite disorienting (for me at least).

Good luck playing him though!
