Corrupted Panther

Keen Smell. The panther has advantage on Wisdom (Perception) checks that rely on smell.

Pounce. If the panther moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the panther can make one bite attack against it as a bonus action.

Soooo Cutee! Creatures within 30 feet of the panther that are not immune to being charmed, or are not of Infernal or Abyssal descent, are enamored with the panther and its magical cuteness. Twice per short rest, the panther purrs loudly and rolls on its back, a creature (that is not abyssal, infernal, or immune to being charmed) must make a DC 12 charisma saving throw, or be compelled to pet the panther. The "Soo Cutee!" ability takes a full combat turn (action, and half the panthers movement)

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.

Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 4 (1d4 + 2) slashing damage.
