Celestial Unicorn Sprite

Teleport (1 per 2 days). The unicorn magically teleports itself and up to one willing creatures it can see within 5 ft. of it, along with any equipment they are wearing or carrying, to a location the unicorn is familiar with, up to 1 mile away. 

Healing Touch (1/day). The unicorn touches another creature with its horn. The target magically regains (1d8 + 2) Hit Points.

Heart Sight. The sprite touches a creature and magically knows the creature's current emotional state. If the target fails a DC 10 Charisma saving throw, the sprite also knows the creature's alignment. Celestials, fiends, and undead automatically fail the saving throw.

Invisibility. The sprite magically turns invisible until it attacks or casts a spell, or until its concentration ends (as if concentrating on a spell). Any equipment the sprite wears or carries is invisible with it.
