Chill

I haven't quite refined this idea, so was wondering if anyone else could contribute to it.
We get a fear debuff from fighting bears and such...why not have a player centered fear, a chill? Perhaps after someone does killing blow, or maybe have top 10 kills, instead of just an alt turning in a scalp for a mask. The killer has an aura or wicked glow about them. They get some kind of chill buff in which they can use it if in combat with others? It could fade over time, so as not overly exploitable. Killing blow already has madness associated with it, so it could limit exploitability.
Or maybe as a witch gets deeper into the arts, they just emit a 'chill' to nearby pilgrims.
Regardless of memorizing a character, some people just look nefarious, or have a bad sense about them no matter how well dressed. Just thought it could be a way to display that in terms of game mechanics(fear), while not necessarily giving away anyone's identity.
