Aguara

Innate Spellcasting. The aguara's innate spellcasting ability is Wisdom (spell save DC 15). She can innately cast the following spells, requiring no material components:

At will: animal friendship, charm person

3/day each: dominate beast, major image, phantasmal force, suggestion

1/day each: hallucinatory terrain

Shapechanger. The aguara can use its action to polymorph into a fox-humanoid hybrid or into a female elf, or back into its true form, which is a werefox. Its statistics, other than its size and speed, 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.

Aguara Transformation. The aguara can perform an exhausting ritual to transform a young elven girl into one of her kind. The spell takes 24 hours to cast. After the casting time the mind of the child is permanently altered and her body goes through the slow process of aguara transformation. The changes brought about by this spell can only be reverted by a Wish spell.

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

Multiattack. (Hybrid or Fox Form Only). The aguara makes two attacks: one with its bite and one with its claws or two with its claws (hybrid).

Claw (Hybrid or Fox Form Only). Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage.

Bite (Fox Form Only). Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage.
