Rampage. When this creature reduces a creature to 0 hit points with a melee attack on its turn, it can take a bonus action to move up to half its speed and make one additional melee attack.

Bloodlust. Once per day, this character can choose to gain advantage on one Wisdom (Survival) check, or one Wisdom (Perception) check.

Mark of the Hunt. Yeenoghu is always aware of this creature's location if they are on the plane of the Abyss. Additionally, The mark of Yeenoghu appears on this creature's forehead for 24-hours after this creature kills a creature. Killing an undead creature or construct does not activate Mark of the Hunt.

This feat is removed from this character if Yeenoghu dies or if this character receives a boon from another demon lord.
