Starlight (aura, light) 15 feet. The glow of the crownbound constellation creates dim light. It can suppress or resume this ability as a free action.

Attack of Opportunity [R]

Speed 40 feet

Melee [>] star greatsword +21 (magical, versatile p), Damage 2d12+10 slashing and starburst

Ranged [>] star composite longbow +18 (deadly d10, magical, reload 0, volley 30 feet), Damage 2d8+7 piercing and starburst

Dazzling Assault [>] (visual) Each enemy in the crownbound constellation's space takes 7d4 bludgeoning damage (DC 23 basic Reflex save). Creatures that fail this save are also dazzled until the end of their next turn.

Starburst (visual) A creature that takes damage from a crownbound constellation's attack must succeed at a DC 23 Fortitude save or be dazzled for 1 minute.

Star Weapons [>] The crownbound constellation reforms its two weapons as +1 striking common or uncommon simple or martial weapons. These star weapons can't be disarmed, broken, dropped, destroyed, or stolen. Ranged star weapons don't require ammunition and those with a reload of 2 have a reload of 0 instead. When the crownbound constellation dies or uses its swarm shape its star weapons disappear.

Swarm Shape [>] (concentrate) The crownbound constellation disperses into a shapeless swarm of Small stars. It drops all held, worn, and carried items. While discorporated, the crownbound constellation can't use attack actions, but it has a fly Speed of 40 feet and can move through areas small enough for its individual stars to fit without having to Squeeze. It can use Swarm Shape again to coalesce back into its normal form, at which point its star weapons reappear.
