Ancient Phoenix

Fiery Death and Rebirth. When the phoenix dies, it explodes. Each creature within 60-feet of it must make a DC 20 Dexterity saving throw, taking 22 (4d10) fire damage on a failed save, or half as much damage on a successful one. The fire ignites flammable objects in the area that aren’t worn or carried.

The explosion destroys the phoenix’s body and leaves behind an egg-shaped cinder that weighs 5 pounds. The cinder is blazing hot, dealing 21 (6d6) fire damage to any creature that touches it, though no more than once per round. The cinder is immune to all damage, and after 1d6 days, it hatches a new phoenix.

Fire Form. The phoenix can move through a space as narrow as 1 inch wide without squeezing. Any creature that touches the phoenix or hits it with a melee attack while within 5 feet of it takes 5 (1d10) fire damage. In addition, the phoenix can enter a hostile creature’s space and stop there. The first time it enters a creature’s space on a turn, that creature takes 5 (1d10) fire damage. With a touch, the phoenix can also ignite flammable objects that aren’t worn or carried (no action required).

Flyby. The phoenix doesn’t provoke opportunity attacks when it flies out of an enemy’s reach.

Illumination. The phoenix sheds bright light in a 60-foot radius and dim light for an additional 30 feet.

Legendary Resistance (3/Day). If the phoenix fails a saving throw, it can choose to succeed instead.

Siege Monster. The phoenix deals double damage to objects and structures.

Elemental Nature. An elder elemental doesn’t require air, food, drink, or sleep.

Multiattack. The phoenix makes two attacks: one with its beak and one with its fiery talons.

Beak. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 15 (2d6 + 8) fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns.

Fiery Talons. Melee Weapon Attack: +13 to hit, reach 15 ft., one target. Hit: 17 (2d8 + 8) fire damage.

Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns. This attack may be used while flying.

Wing slash Attack. Melee Weapon Attack: +13 to hit reach 15 ft., up to three targets. Hit: 19 (2d10 + 8) slashing damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 5 (1d10) fire damage at the start of each of its turns. This attack may be used while flying.

Counter Attack.  As long as in movement range, this creature can move over to the attacker if they land a successful hit against said creature and launch a counter attack against them.
