Multiattack

The drake makes one Bite attack and two Claw attacks, or it makes four Searing Star attacks. If two Searing Star attacks hit one creature, that creature must succeed on a DC 18 Constitution saving throw or be blinded until the end of its next turn.

Bite

Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 16 (2d10 + 5) piercing damage plus 18 (4d8) force damage.

Claw

Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage plus 18 (4d8) force damage.

Searing Star

Ranged Spell Attack: +12 to hit, range 120 ft., one target. Hit: 14 (2d6 + 7) radiant damage plus 9 (2d8) force damage.

Planar Traveler

The star drake can transport itself to a different plane of existence. This works like the plane shift spell, except the drake can affect only itself and can't use this action to banish an unwilling creature to another plane.

Plane-Altered Breath (Recharge 5-6)

The drake exhales raw magic in a 60-foot cone. Each creature in that area must make a DC 18 Dexterity saving throw, taking 55 (10d10) force damage on a failed save, or half as much damage on a successful one.
