Flyby. The faerie doesn't provoke opportunity attacks when it flies out of an enemy's reach.
Spellcasting. The faerie casts one of the following spells, requiring no material components and using Charisma as the spellcasting ability (spell save DC 13):
At will: prestidigitation
1/day: silent image
Needle Blade. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit:7 (1d4 + 5) piercing damage.
Magic Mockery. The faerie hurls magical taunts at one creature it can see within 60 feet of itself. The creature must succeed on a DC 13 Wisdom saving throw or take 3 (1d6) psychic damage and have disadvantage on attack rolls and ability checks until the start of the faerie's next turn.
Tricksy Parry. Immediately after taking damage, the faerie reduces the damage taken by 2 (1d4).
The faeries of Eldraine are winged, elfin creatures similar to sprites or pixies. Unpredictable, unreliable, and amoral, they lurk in the wilds and harass travelers they perceive as intruders.
