Sprite

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.

Charisma Saving Throw: DC 10, one creature within 5 feet the sprite can see (Celestials, Fiends, and Undead automatically fail the save). Failure: The sprite knows the target’s emotions and alignment.

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.

The sprite casts Invisibility on itself, requiring no spell components and using Charisma as the spellcasting ability.
