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

Fade Away. At the end of its turn, the fox can turn invisible until the start of its next turn.

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

At will: Mind Sliver, Minor Illusion

3/day: Misty Step

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6+4) piercing damage.

Vanishing Gaze. The fox's eyes and the gem on its forehead glow and focus on up to 3 objects or creatures within 30 ft. The gem emits a soft teal pulse in the direction of the targets, turning them invisible. A creature can succeed on a DC 15 Wisdom saving throw to resist the effect. Anything an affected creature is wearing or carrying becomes invisible for the duration as well, as long as it is on the creature’s person. A creature can attack, cast spells, and take damage while invisible from Vanishing Gaze. The effect ends if the targets are more than 120ft of the fox or if the fox loses concentration on Vanishing Gaze (as if concentrating on a spell).

Gem Surge (3/Day). The gem in the fox's head surges with power. The fox casts Mind Sliver.

Skirmisher. The fox is difficult to pin down during a fight. It can move up to half its speed as a reaction when an enemy ends its turn within 5 feet of the fox. This movement doesn’t provoke opportunity attacks.
