Apex Seething Bazelgeuse

Carpet Bomb. For every 20 feet the bazelgeuse flies, it dislodges an explosive scale which lands in an unoccupied space directly below it.

Dive Attack. If the bazelgeuse is flying and dives at least 30 feet straight toward a target and then hits it with a headbutt attack, the attack deals an extra 4 (1d8) damage to the target.

Explosive Scales. The bazelgeuse scales, when dislodged from its body, act as a time bomb. On initiative count 20 (losing all initiative ties) all scales explode dealing 14 (4d6) fire damage to all creatures in a 10-foot radius of them.

Shed. Whenever the bazelgeuse makes a melee weapon attack it dislodges an explosive scale which lands in an unoccupied space with 5 feet of its location.

Wounded Fury. While it has 100 hit points or fewer, the bazelgeuse enters a "superheated" state gaining advantage on attack rolls. In addition, Explosive Scales grow, increasing their explosion radius by 5 feet and deal an extra 1d6 fire damage.

Multiattack. The bazelgeuse makes three attacks: one with its headbutt, one with its wing, and one with its tail.

Headbutt. Melee Weapon Attack. +13 to hit, reach 10 ft., one target. Hit: 19 (3d8 + 6) bludgeoning damage.

Wing. Melee Weapon Attack. +13 to hit, reach 10 ft., one target. Hit: 22 (3d10 + 6) bludgeoning damage.

Tail. Melee Weapon Attack. +13 to hit, reach 15 ft., one target. Hit: 16 (3d6 + 6) bludgeoning damage and gains 1 frenzy charge.

No Man's Landing (Recharging 6). The bazelgeuse soars 30 feet into the sky while scattering 15 explosive scales in a 60-foot radius around it, that are at least 15 feet apart. It then comes crashing back down to the ground creating a 20-foot wide explosion. Each scale in the explosions area is destroyed, and each creature in that area must make a DC 22 Dexterity saving throw, taking 63 (14d8) fire damage on a failed save, or half as much on a successful one.

The bazelgeuse can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The bazelgeuse regains spent legendary actions at the start of its turn.

Fling. The bazelgeuse dislodges 3 explosive scales and sends them flying with its tail. Choose a location within 60 feet of the bazelgeuse, each scale lands in an unoccupied space within 15 feet of that location.

Fire Breath (Costs 3 Actions). The bazelgeuse exhales fire in a 60-foot cone. Each creature in that area must make a DC 22 Dexterity saving throw, taking 46 (7d12) fire damage on a failed save, or half as much damage on a successful one.
