Hit Die. Your hit die is a d4 (average of 3) regardless of your class.
Diminutive Dexterity. Your maximum Dexterity Score is 30 instead of 20.
Giant's Protection. While you occupy the same space as a friendly creature that isn't incapacitated you have three-quarters cover, and if you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed.
Ability Score Increase. DEX+5, CON-4. Pixies get CHA+2, Sprites get INT+2.

Skills Perception +3, Stealth +8
Senses Passive Perception 13

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.
