Any unprotected, non-magical flame within 30 feet of it is extinguished. The area within 30 feet of it is considered magical hard terrain. Any non-spell ranged attack that hits the Thunderbird has its damage reduced by 11 (2d10).

If the attack hits, that creature takes the bite's damage, it is swallowed, and the grapple ends. While swallowed, the creature is Blinded and Restrained, it has total cover against attacks and other effects outside the Thunderbird, and it takes 21 (6d6) acid damage and 9 (2d8) thunder damage at the start of each of the Thunderbird's turns. If the Thunderbird takes 30 damage or more on a single turn from a creature inside it, the Thunderbird must succeed on a DC 15 Constitution Saving Throw at the end of that turn or regurgitate all swallowed creatures, which fall Prone in a space within 10 feet of the Thunderbird. If the Thunderbird dies, a swallowed creature is no longer Restrained by it and can escape from the corpse using 15 feet of movement, exiting Prone. > > ***Frightful Presence.*** Each creature of the Thunderbird's choice that is within 120 feet of it and aware of it must succeed on a DC 18 Wisdom saving throw or become Frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the Thunderbird's Frightful Presence for the next 24 hours. > > ***Lightning Breath (Recharge 5-6).*** The Thunderbird exhales a line of lightning that is 60 feet long and 5 feet wide. Each creature in that line must make a DC 18 Dexterity saving throw, taking 56 (16d6) lightning damage on a failed save, or half as much damage on a successful one.

Each creature in that sphere must succeed on a DC 18 Constitution Saving Throw or take 44 (10d8) thunder damage and be knocked Prone. On success, take half damage and not knocked prone. If the creature fails by 10 or more, it is Stunned until the end of its next turn. > ### Legendary Reactions > > * If a character hits the Thunderbird twice in a row with a non-spell ranged attack, the Thunderbird grabs the projectile and throws it back.

Thunderbirds bring the storm on their wings. In times of drought, they are welcomed with joy and celebration. In other times, they are placated with gifts in hopes that they might leave quickly before flooding begins. When angered, thunderbirds can call down hurricanes and lay waste to entire villages, so in regions where these birds dwell, many villages maintain extensive rituals designed to appease and honor the local thunderbirds. Thunderbirds nest near the base of waterfalls, where the constant thrum of crashing water prepares the hatchlings for a life at the heart of a storm. Once the chicks have hatched, their parents carry the offspring to nests at the top of mountains, where the young are struck by their first bolts of lightning and learn the mysteries of the storm.
