Expert Aerialist. The mystaran dragonfly has advantage on Dexterity (Acrobatics) checks when flying.

Keen Sight. The mystaran dragonfly has advantage on Wisdom (Perception) checks that rely on sight.

Multiattack. The mystaran dragonfly makes two attacks: one with its bite and one with its breath weapon. If the dragonfly uses both attacks against the same target, the target has disadvantage on its saving throw against the breath weapon.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.

Breath Weapon. The mystaran dragonfly breathes at a target within 5 feet. The target must make a DC 13 Dexterity saving throw, with disadvantage if the dragonfly used Multiattack to attack the target with its bite. The target takes 6 (1d12) lightning damage on a failed save, or half as much damage on a successful one.

Darting Flight. The mystaran dragonfly can disengage or dash as a bonus action when flying. It cannot use Darting Flight if it used Dodging Flight after the start of its previous turn.

Dodging Flight. If a creature of at least Small size attempts a melee attack against a mystaran dragonfly, or the dragonfly is targeted by a ranged weapon of similar size such as a giant-hurled boulder, the dragonfly can try to dodge out of the way as a reaction. The mystaran dragonfly makes a Dexterity saving throw with advantage (it loses this advantage when mounted or grappling an opponent). If the saving throw beats the attack roll or DC of the attack the mystaran dragonfly takes no damage and flies up to 30 feet.
 If a mystaran dragonfly is carrying or grappling a creature that is too heavy for the dragonfly to fly with, it must release the creature to use Dodging Flight. If the dragonfly is grappling a creature light enough to carry through the air, the grappled creature can make an escape check as a free action. If it fails, the dragonfly may fly away with its victim.
