Actions

Longsword. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit:1 slashing damage.

Shortbow. Ranged Weapon Attack: +6 to hit, range 40/160 ft., one target. Hit:1 piercing damage, and the target must succeed on a DC 10 Constitution saving throw or become poisoned for 1 minute. If its saving throw result is 5 or lower, the poisoned target falls unconscious for the same duration, or until it takes damage or another creature takes an action to shake it awake.

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.

Lore

In secret groves and shaded glens, tiny sprites with dragonfly wings flutter. For all their fey splendor, however, sprites lack warmth and compassion. They are aggressive and hardy warriors, taking severe measures to ward strangers away from their homes. Interlopers that come too close have their moral character judged, then are put to sleep or frightened off.
