  Curse of the Jackal Lord: When a creature that can see Jackal Head's eyes starts its turn within 30 ft. of Jackal Head, it can force the creature to make a DC 14 Constitution saving throw if Jackal Head isn't Incapacitated and can see the creature. If the saving throw fails by 5 or more, the creature is instantly turned into a Jackal. Otherwise, a creature that fails the save begins to turn into the animal and is Restrained. The Restrained creature must repeat the saving throw at the end of its next turn, becoming fully transfromed into a Jackal on a failure or ending the effect on a success. The animal transformation lasts until the creature is freed by the Greater Restoration spell, polymorph spell, or other magic. A creature that successfully saves against the effect is immune to Jackal Head's gaze for the next 24 hours. Undead and creatures immune to polymorph aren't affected by it.
  Sneak Attack: Once per turn, Jackal Head can deal an extra 5d6 damage to one creature it hits with an attack if it has advantage on the attack roll. The attack must use a finesse or a ranged weapon. Jackal Head doesn't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn’t incapacitated, and Jackal Head doesn’t have disadvantage on the attack roll.

In a city of cut throats, thieves, and scam artists, a king pin rises with a tyrannical grip and a fearful power in his gaze. Jackal Head is a particularly skilled and deadly jackalwere, though his namesake stems from the metal dog shaped helmet he wears. The sadistic crime boss owes his inception to a persistent curse placed on the land. A Jackal Lord must always exist and where one falls, a new one ascends, transformed from the most dangerous of villains living in the local. Where Jackal Head can't persuade a business deal, he bullies them into submission, where he can't use violence, he uses his supernatural gaze to transform his enemies into harmless jackals to torment and control at his leisure. Just be sure, to put this criminal down is to potentially give rise to a more dangerous Jackal Lord.
