Shapechanger. The werejaguar can use its action to polymorph into a jaguar, or back into its true form, which is a jaguar-humanoid hybrid. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Keen Hearing and Smell. The werejaguar has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. The werejaguar has advantage on an attack roll against a creature if at least one of the werejaguar's allies is within 5' of the creature and the ally isn't incapacitated.

Pounce. If the werejaguar moves at least 15 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 14 Strength saving throw or be knocked prone. If the target is prone, the werejaguar can make one bite attack against it as a bonus action.
