Traits

Immutable Form. The warbler is immune to any spell or effect that would alter its form.

Telepathic Bond. While the warbler is on the same plane of existence as its master, it can magically convey what it senses to its master, and the two can communicate telepathically with each other.

Actions

Claw. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit:4 (1d4 + 2) slashing damage.

Calming Mist (Recharge 5–6). The warbler releases a calming gas in a 5-foot-radius sphere centered on itself. Each creature in that area must succeed on a DC 11 Charisma saving throw or become charmed by the warbler for 1 minute. While charmed in this way, the creature is incapacitated and has a speed of 0.

Lore

Metallic warblers resemble songbirds and serve as clandestine agents of their creators, keeping watch over communities without directly intervening. Their telepathic bond lets them summon their dragon creators in case of dire need.
