Infernal Mark of Doom. The Infernal Cacodemon chooses a creature it can see within range and mystically marks it as its quarry for 1 minute. Until the mark ends, it deals an extra (1d6) psychic damage to the target whenever it hits with an attack and has advantage on any Wisdom (Perception) or Wisdom (Survival) check it makes to find the marked creature. If the target drops to 0 Hit Points before this effect ends, the knight can use a Bonus Action on a subsequent turn to mark a new creature.

Infernal Fury. After making a melee attack infernal creatures can move up to half their base speed as a Reaction without provoking opportunity attacks.
