The Fallcall passive you get after you cast Death Knighting is not giving bonus damage against feared enemies. I tested it like this:

1. Death Knighting vs Prinny
2. Fear inflict the Prinny
3. Do damage
4. Repeat the attack without the Death Knighting setup

Fallcall's listing in the Cache dump (nothing else relevant to Death Knighting pops up for me):
/obj/skill/passive/fallcall (0)
