Clockwork Owl

Dispel Vulnerability. If the clockwork owl is targeted by dispel magic or a similar spell or effect that banishes magic, it must succeed on a Constitution saving throw equal to the caster's spell save DC. On a failure, the owl takes 11 (2d10) force damage and is stunned until the end of its next turn.

Lifelike. While the owl is viewed from a distance and isn't performing obviously abnormal activities, it resembles an ordinary creature. A creature within 30 feet of it can discern its true nature with a successful DC 15 Intelligence (Nature) check.

Magic Resistance. The clockwork owl has advantage on saving throws against spells and other magical effects.

Flyby. The owl doesn't provoke opportunity attacks when it flies out of an enemy's reach.

Keen Hearing and Sight. The owl has advantage on Wisdom (Perception) checks that rely on hearing or sight.

Talons. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 1 slashing damage.
