Cherub

Innate Spellcasting. The Cherub can cast the Light cantrip, using only somatic components.

OR

Glowing. As long as the Cherub is conscious and in it's true form, it glows as if the Light cantrip was cast on it.

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

Divine Sense. The Cherub has advantage on all ability checks related to determining if an illusion is real or not. Instead of examining one illusion to determine if it's real as an action, the Cherub can do so once per turn as a free action.

 Cherub's Bow. Ranged Weapon Attack: +5 to hit, range 60/180 ft., one target. Hit: 1 radiant damage. Target must succeed on DC 11 Wisdom saving throw or become charmed by either the first creature is sees, the first potential mate it sees, or a creature of the Cherubs choice, within the target's current sight (GM's discretion). This lasts 10 minutes, or until the creature the target is charmed to harms the target. The target can choose to fail the saving throw. If you or your companions are fighting the target, the Wisdom saving throw is made with advantage. If this attack would reduce the target to 0 hit points, instead it takes no damage and automatically fails the saving throw. 

Cherub's Intuition. The Cherub can touch one willing target and magically determine if it's lying. If the target fails a DC 10 Charisma saving throw, the Cherub also knows what the target loves, and what it could never love.

Shapechanger. The Cherub can use its action to polymorph into a form that resembles a baby of any humanoid race (speed 5 ft.), a dove (20 ft., fly 60 ft.), a lion cub/kitten (20 ft., climb 20 ft.), or back into its true form. Its statistics are the same in each form, except for the speed changes noted. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

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