Can someone explain me how the legion frenzy works?

[apriori]

I just purchased the legion dlc and I don't quiet understand how stabbing survivors while frenzying works. I have to stab them three times to take someone down? if they unhook someone, how many frenzy stabs does it take me to incap the survivor again?
Thanks
and also, which perks make him a badass killer

Simply put: It doesn't work.

-In frenzy, you inflict Deep Wound status on the survs, but can't down them.
-Consecutive frenzy hit take 1/4 of the bleed out timer, but if you hit the same surv twice, your frenzy end immediatly.
-The bleed out timer does not go down while you chase them.
-They have to perform the mending action to stop the bleeding, wich freeze the bleedout timer at 1% no matter what, does not require skillchecks and is not considered "healing" so it does not synergyze with any perk.

So what will happen is that inexperienced survivor will panic against Legion and do stupid mistakes allowing you to catch them eventually.
Experienced survivor, will moslty ignore the bleedout because of how harmeless it truly is, unless you are using Frank's Mixtape, wich make you remove bigger chunks of the bleedout timer with multiple frenzy hits.

The "correct" way to play Legion the way he is designed, is to run into a group of survs and stab as many as you can. Then you try your best to finish one of them with your slow speed. After that if they are smart, they will split, making your special ability near useless. Or you use the magical crutch mixtape.

Also because of the end of frenzy slow down and inability to see scratch marks, I found Bloodhound usefull to not lose the survivors you just stabbed. Certainly not the best perk, but handy while you are grinding through the bloodweb.

Monitor and Abuse is amazing on her, sneak on up them to get a chain going and with the extra TR you can see further, Thana, Sloppy are great subs for ruin to slow the game down, and stridor incase they juke you,
