Innate Spellcasting. The thunderbird’s innate spellcasting ability is Charisma (Spell save DC 13). It can innately cast the following spells, requiring no material components:

  • At will: lightning bolt, misty step, resistance
  • 1/day: control weather (creates thunderstorms only)

Storm Shroud. During a thunderstorm, lightning coils around the thunderbird, granting it a +2 magical bonus to its AC.

Sun’s Messenger. The thunderbird exudes bright light and is treated as always having the daylight spell cast on it.


Multiattack. The thunderbird makes two attacks: one with its beak and one with its talons.

Beak. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (1d6+4) piercing damage plus 3 (1d6) lightning damage.

Talons. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 7 (2d6+4) slashing damage plus 7 (2d6) lightning damage


Rumored to hail from a great mountain that floats in the sky, the thunderbird is a heavenly being of might and bravery, appearing during great deeds as a positive omen. Thunderbirds usually herald a cleansing storm meant to route away evildoers.

Stolen from the Sea. Talos, the God of Storms, created the first clutch of thunderbird eggs in the skull of a storm giant deep in the ocean depths. Mielikki knew that Talos would only use the thunderbirds for evil, so she tasked a team of bronze dragons to retrieve the eggs. The dragons took the eggs to the Greypeak Mountains and guarded them until they hatched. Thunderbirds are always at risk of being captured by Talos, who sends followers out to scavenge for other nests.

Heroic Omen. To dream of a thunderbird is a sign of leadership. Children who see visions of the thunderbird during stressful times are destined to grow into powerful leaders. Priests of Mielikki are known to welcome those “touched by the storm” into their communes, allowing their leadership skills to nurture and grow.

Storm’s Wrath. A thunderbird in battle is no easy opponent. They rarely engage unless they conjure a storm, from which they shine like a beacon—a thunderbird never hides in the clouds, but lets its presence be known across the battlefield as it shines through the darkest nights. Thunderbirds keep their distance, sending down bolts of lightning to disintegrate the wicked. In close combat, a thunderbird is rippling with electric energy as it pecks and claws at opponents.
