Arctic Fox (CotFS)

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

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

1/summon each: Calm Emotions, Detect Evil and Good, Frostbite, Ray of Frost.

For spells that use the caster's level, use the Druid leader's level to determine the spell's extra abilities/damage. For spells that use spell levels, they can be cast up to half of the Druid leader's level, rounded down.

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 fox has advantage on saving throws against spells and other magical effects.

Pack Tactics. The 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.

Familiar. The fox can serve another creature as a familiar, forming a magic, telepathic bond with that willing companion. While the two are bonded, the companion can sense what the fox senses as long as they are within 1 mile of each other. While the fox is within 10 feet of its companion, the companion shares the fox's Magic Resistance trait. At any time and for any reason, the fox can end its service as a familiar, ending the telepathic bond.

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.

Transform Release.  When the transformation is released, the creature's HP reaches 0, or time runs out on the transformation, this fox separates back into the individual Red Foxes that combined their power to create this creature, as mentioned in the Circle of the Fox Shepherd.

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.
