How would you feel about a blood-based killer?
Not necessarily a Vampire but a blood mage.

>Movement Speed: 4.6 m/s (standard Killer speed, with potential bursts from abilities).
>Terror Radius: 32 meters.

First you have to M1 a survivor in order to make the abilities work, he has long Freddy Krueger-like claws that allow him to slice the survivors in order for them to bleed.

>Transfusion
Once you slice a survivor, you are able to damage them with "transfusion". Makes them scream, making them unable to perform any action so predropping pallets would be preferred. Would slow them down by 50%.

>Tides of Blood
I imagine him having some sort of ability where stacked blood pools allow him to teleport to healing survivors' pools of blood so in order to counter him you'd have to take healing perks to do it fast enough, obviously he would be able to teleport faster once he stacks his ability. (still have to think on how would his stacking ability work)

>Sanguine Pool
Makes you invulnerable to pallets for a short period of time, you turn yourself into a pool of blood and allows you to bypass a fallen pallet, you also have decaying movespeed and any survivor that is within the Pool will be slowed by 20%.

This whole concept is messy and not well thought through but I'd like to see this bastard in this game and have someone who resembles a Vampire more and not a shape shifting Werewolf with pillars of fire.
