Traits
When the emissary drops to 0 hit points, its body melts away. A greater star spawn emissary instantly appears in an unoccupied space within 60 feet of where the lesser emissary disappeared. The greater emissary uses the lesser emissary's initiative count.
If the emissary fails a saving throw, it can choose to succeed instead.
The emissary doesn't require air, food, drink, or sleep.
Actions
The emissary makes three attacks.
Melee Weapon Attack: +11 to hit, reach 15 ft., one target. Hit: 16 (2d10 + 5) piercing damage plus 13 (3d8) acid damage.
Ranged Spell Attack: +13 to hit, range 120 ft., one creature. Hit: 18 (2d10 + 7) psychic damage.
