    Traits

    Titanic Fiery Wheel. Wanyudo appears as an enormous, flaming wheel up to 12 feet in diameter, with a wrathful face in the center. It hovers freely, ascending to high altitudes as needed.

    Nightmare Presence (Greater). Each creature that can see Wanyudo or starts its turn able to see Wanyudo must succeed on a DC 19 Wisdom saving throw or become frightened for 1 minute. While frightened:

    • The creature’s speed is halved.

    • It takes 14 (4d6) psychic damage at the start of each of its turns.

    A frightened creature repeats the save at the end of each turn, ending the effect on success. Once a creature succeeds or the effect ends, it’s immune to Nightmare Presence for 24 hours.

    Infernal Flame Body. Any creature that touches Wanyudo or hits it with a melee attack within 10 feet takes 14 (4d6) fire damage. Additionally, Wanyudo can occupy the same space as other creatures. If it ends its turn in the same space as a creature, that creature must make a DC 19 Dexterity save or take 21 (6d6) fire damage.

    Sunlight Banishment. At dawn, Wanyudo dissolves in a swirl of flame. Any ongoing effects end. It reappears at dusk near where it vanished, unless destroyed or exorcised.

    Actions

    Multiattack. Wanyudo makes four Spoke Slash attacks or three Spoke Slash attacks and uses Hellish Overrun if available.

    Spoke Slash. Melee Weapon Attack: +16 to hit, reach 15 ft., one target.

    Hit: 21 (3d8 + 9) slashing damage plus 10 (3d6) fire damage. If the target is frightened, add 14 (4d6) psychic damage once per turn as the victim’s terror intensifies.

    Hellish Overrun (Recharge 5-6). Wanyudo hurtles up to 60 feet in a straight line, passing through creatures’ spaces. Each creature in that path must make a DC 19 Dexterity saving throw, taking 49 (14d6) fire damage on a fail, or half on success. A creature failing by 5 or more is knocked prone and pushed 20 feet to the side.

    Bonus Actions

    Severing Curse (Greater) (1/Short Rest). Wanyudo curses one creature within 60 feet that it can see. The target must succeed on a DC 19 Constitution saving throw or suffer for 1 minute:

    • Speed reduced by 20 feet.

    • Each time it takes the Attack action, it suffers 14 (4d6) psychic damage.

    • It can repeat the save at the end of each of its turns, ending the effect on success.

    Reactions

    Rageful Glare (Greater). When Wanyudo takes damage from a creature it can see, it forces that creature to make a DC 19 Wisdom saving throw. On a failed save, that creature is frightened of Wanyudo until the end of its next turn and takes 14 (4d6) psychic damage.

    Lair or Environmental Effects (Optional)

    Flaming Skies. At initiative count 20, scorching embers rain in a 20-foot radius centered on a point Wanyudo chooses. Each creature in that area must make a DC 19 Dexterity save or take 14 (4d6) fire damage. Shrieking Souls: Hellish wails echo within 60 feet. Hostile creatures have disadvantage on saving throws against Wanyudo’s Nightmare Presence or Rageful Glare.

    Lore

    This Wanyudo has grown into a cataclysmic force of vengeance and flame, imposing a grave threat even to epic heroes.

    Afearsome figure of old, Wanyudo (“Wheel Monk”) is deeply rooted in ancient Buddhist notions of karma, retribution, and punishment for one’s sins. He appears as a blazing, oversized wheel of a cart, its center bearing a twisted human face— often likened to a stern monk or the tormented spirit of a sinner condemned to an eternal, rolling inferno. His emergence is bound to Buddhist concepts of justice, and his role is to punish those who break moral laws and commit evil deeds.

    Many accounts of Wanyudo’s origin point to people who committed horrific crimes in life. In one of the most widespread traditions, this yokai was once a pitiless daimyo (feudal lord) or a cruel Buddhist monk, infamous for oppressing the innocent, abusing peasants, and bending authority to personal gain.
