Abnegation (1/Encounter). If the jaguar fails a saving throw, it can succeed instead. Alternatively, it can expend this trait to safely pass through conjurations and evocations until the end of its next turn.
Crepusculous and Adumbral. Though clearly a beast of flesh and blood, the edges of its body drift away in wisps of shadow. The jaguar has advantage on saving throws against spells and other magical effects. Its weapon attacks are magical. Magical darkness doesn’t impede its darkvision .
Cursed Blood. You stab the jaguar’s flayed and unnatural muscles and sinew. Pulsating veins and arteries snap open, and its black blood sizzles and releases a horrid stench where it stains the ground. Whenever the jaguar takes piercing or slashing damage, it sprays out dark blood. Each creature within 5 feet of the jaguar cannot regain hit points until the end of its next turn. Additionally, until the end of the jaguar’s next turn, each space it moves through becomes contaminated difficult terrain until it is scrubbed clean. Each time a creature enters this contaminated difficult terrain or ends its turn there, it cannot regain hit points until the end of its next turn.
Keen Smell. The jaguar has advantage on Perception checks that rely on smell.
No Escape. You can see the muscles of the skinless jaguar flex as it swipes a claw at your leg and trips you. If the jaguar hits with an opportunity attack, the target must succeed on a DC 12 Strength saving throw or be knocked prone .
Volatile Existence. When the jaguar is reduced to 0 HP, it dies. Any witchoil it has that is not ensouled degenerates into regular oil; its ensouled witchoil can still be gathered up.

ACTIONS

Multiattack. The jaguar makes two Claw attacks. If the target is prone , it instead makes two Claw attacks and a Bite attack.
Bite. Every inch of the jaguar’s bared skull is visible to you as the beast clamps down. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 8 (1d12 + 2) piercing damage. If the target is a prone Large or smaller creature, it is grappled (escape DC 12), and the jaguar cannot bite another target until this grapple ends.
Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 9 (2d6 + 2) slashing damage

TECHNOLOGICAL WEAKNESSES

Command Collar (Insight DC 12). The creature shrinks away whenever anyone is near its collar. A creature that is grappling the jaguar can grab its collar and spend a bonus action to attempt a DC 13 Charisma (Animal Handling) check. On a success, for 1 minute, the jaguar is charmed by the creature that subjugated it and obeys that creature’s verbal commands, though it will defend itself if attacked, ignoring any commands. If the subjugation attempt fails, the creature can try again, assuming it’s fine getting mauled in the meanwhile. While the jaguar is charmed, the creature that charmed it can remove its witchoil heart or safely open it to refill it with ensouled witchoil. Afterward, the jaguar becomes loyal to that creature for a week.
Witchoil Heart (Arcana DC 12). A steel plate is bolted directly into the ribcage of the poor creature, and black witchoil pumps across it in pulses, like the beating of a heart. If the jaguar’s Speed is 0, a creature within reach can spend an action to attempt a DC 13 Strength check to remove the steel plate covering the jaguar’s heart. On a success, the jaguar takes 10 ongoing damage, and the next attack that deals damage to the jaguar kills it.
