Undead Fortitude. If damage reduces the Zombie King of Feathers to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.

See Invisibility. The Zombie King of Feathers can see invisible creatures and objects as if they were visible.

Legendary Resistance (3/day). If the Zombie King of Feathers fails a saving throw, it can choose to succeed instead.

Multiattack. The Zombie King of Feathers makes two attacks: one with its bite and one with its tail. It can’t make both attacks against the same target.

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 33 (4d12 + 7) piercing damage. If the target is a Medium or smaller creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained and the Zombie King of Feathers can’t bite another target or disgorge zombies.

Tail. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 20 (3d8 + 7) bludgeoning damage.

Summon Swarm (Recharge 5-6). The Zombie King of Feathers exhales a swarm of rot grubs that forms in a space within 20 feet of it. The swarm acts as an ally of the Zombie King of Feathers and takes its turn immediately after it. The swarm disperses after 1 minute.

Teleport. The Zombie King of Feathers teleports to an unoccupied space it can see within 30 feet of it.

Disgorge Zombie. As a bonus action, the Zombie King of Feathers can disgorge a normal zombie, which appears in an unoccupied space within 10 feet of it. The disgorged zombie acts on its own initiative count. After a zombie is disgorged, roll a d6. On a roll of 1, the Zombie King of Feathers runs out of zombies to disgorge and loses this trait. If the Zombie King of Feathers still has this trait when it dies, 1d4 normal zombies erupt from its corpse at the start of its next turn. These zombies act on their own initiative count.
