Ceronyr, Beast of the Heorot

Feather Step. Ceronyr can leap up to his speed without a check, and can treat any surface, including leaves or falling snow, as solid ground.

Path of the Forest-Crowned (Mythic Trait, 1/Day). When Ceronyr is reduced to 0 hit points, he doesn't die or fall unconscious. Instead, he gains 126 temporary hit points and all of his wounds appear to heal.

For the next hour, he can use 5 feet of movement to step magically into one living tree within 5 feet and emerge from a point at the same height on a second living tree within 60 feet of the first tree.

Legendary Resistances (3/Day). If Ceronyr fails a saving throw, he can choose to succeed instead.

Multiattack. Ceronyr makes three melee attacks, one of which he may replace with a use of his Golden Wind.

Bone-Crown Rush. Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 22 (5d6 + 5) piercing damage and the target must succeed on a DC 18 Strength saving throw or be knocked prone.

On a hit or miss, the target is pushed 10 feet away.

Rearing Kick. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) slashing damage.

A prone target takes an additional 9 (2d8) bludgeoning damage.

Golden Wind (Concentration). One creature within 15 feet of a patch of wildflowers created by Ceronyr's Wildflower Tread is enveloped by swirling winds, dense with pollen, that heavily obscure the area beyond them.

The creature may spend half its movement to make a DC 18 Strength saving throw. On a success, the creature escapes, coated in pollen. On a failure, the creature falls prone.

Falling Slam (Recharge 5-6). Ceronyr leaps up to 30 feet into the air, then falls to the ground.

Each creature in the space where he lands must succeed on a DC 18 Dexterity saving throw or be knocked prone and take 7 (2d6) bludgeoning damage for each 10 feet that Ceronyr fell, or take half as much and move to the nearest unoccupied space on a success.

Elusive Sidle. When a creature enters Ceronyr's reach, he can move up to half its speed in any direction other than directly away from the creature without provoking Opportunity Attacks.

Burgeoning. When a creature covered in pollen from Ceronyr's Golden Wind falls prone, he can magically causes tiny roots to sprout from its flesh and anchor it to the ground, restraining it until the end of its next turn (escape DC 18).

Punishing Charge. When a creature picks up an object dropped due to his Hard Stare, Ceronyr can move up to half his speed directly toward the creature and make a melee attack against it.

Ceronyr can take 3 legendary actions, choosing from the options below.

Wildflower Tread. The ground beneath Ceronyr's feet blooms with magical wildflowers that last for an hour before withering. A creature that starts its turn standing in the flowers gains 11 (2d10) temporary hit points.

Hard Stare. One creature within 30 feet that Ceronyr can see must succeed on a DC 17 Wisdom saving throw or drop one item it is holding.

Unearthly Scream (Costs 2 Actions). Ceronyr releases a haunting sound. Each creature within 30 ft. must succeed on a DC 17 Wisdom saving throw or be unable to take hostile action on its following turn.
