Celestial Fox (or "Moon Fox")

Keen Senses. The celestial fox has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Innate Spellcasting. The fox's innate spellcasting ability is Charisma (spell save DC 14). It  can innately cast the following spells, requiring no components:

1/day each: animal friendship, calm emotions, detect evil and good.

Limited Telepathy. The fox can magically communicate simple ideas, emotions, and images telepathically with any creature within 50 feet of it who can understand at least one language or that has an Intelligence score of 3 or higher.

Magic Resistance. The celestial fox has advantage on saving throws against spells and other magical effects.

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

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage.

Healing Kisses (1/short rest). The fox licks or 'kisses' another creature (or itself) and the target magically regains 3 (1d4 +1) hit points. In addition, the kisses neutralize any poisons afflicting the target.

Moon-touched. While in Darkness or Dim Light, as an action, the celestial fox can cause its coat to appear any shade reflected in the moon's phases, ranging from glowing silvery white (emitting Bright or Dim Light within a 5-foot radius) to frosted grey to charcoal black. The fox can use this ability to receive advantage on Dexterity (Stealth) checks made in Dim Light and Darkness.

Canny. The fox can move up to half its speed as a reaction when an enemy ends its turn within 5 feet of it. This movement doesn’t provoke opportunity attacks.
