Traits

Heaven-Forged Body. Beomeo can’t be grappled, restrained, or knocked prone, and it can move through a space as narrow as 1 inch without squeezing.

Golden Brilliance. Bright light (PHB p. 255/292) in a 30-foot radius and dim light for another 30 feet surrounds Beomeo. A creature that starts its turn in the bright light and harbors hostile intent toward Beomeo must succeed on a DC 19 Wisdom saving throw or be blinded until the start of its next turn. Beomeo can suppress or restore this light (no action required).

Five-Colored Cloud. Ranged attacks against Beomeo have disadvantage, and it has advantage on Dexterity saving throws. While Beomeo is in the air or water, it has half cover (+2 AC).

Eyes of Enlightenment. Beomeo automatically succeeds on Wisdom saving throws against illusions, and magic can’t hide a creature from its truesight.

Innate Spellcasting. Beomeo’s spellcasting ability is Charisma (spell save DC 19, +11 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

At will: detect evil and good (PHB, p. 231/261), light (PHB p. 255/292), sanctuary (self only; PHB p. 272/313)

3/day each: daylight (PHB p. 230/260), dispel evil and good (PHB p. 233/263), calm emotions (PHB p. 221/249)

1/day each: heal (PHB p. 250/284), holy aura (PHB p. 251/286)

Water Blessing. A creature that spends 1 hour swimming or wading peacefully in a pool or spring shared by Beomeo is cured of all diseases and gains the benefit of a greater restoration spell.

Actions

Radiant Pulse. (Recharge 5–6). Beomeo releases a wave of benevolent light. Choose up to eight creatures it can see within 60 feet. Each willing creature regains 25 (5d8 + 2) hit points and is freed from the charmed, frightened, and stunned conditions. Hostile creatures instead take 25 (5d8 + 2) radiant damage and must succeed on a DC 19 Wisdom saving throw or be pacified—treated as under the effects of calm emotions—until the end of Beomeo’s next turn.

Reactions

Mirror of Virtue. When Beomeo is targeted by an attack or harmful spell, it can force the attacker to make a DC 19 Charisma saving throw. On a failure, the attacker must choose a different target for the attack or spell, or the effect is wasted.

Legendary Actions

Beomeo can take 2 legendary actions, choosing from the options below. Only one option can be used at a time and only at the end of another creature’s turn. It regains spent legendary actions at the start of its turn.

Move. Beomeo swims or flies up to half its speed.

Gleaming Shift. Beomeo casts detect evil and good or light.

Blessing Flash (Costs 2 Actions). Beomeo targets one creature it can see within 60 feet. The target gains 10 temporary hit points and advantage on its next attack roll, ability check, or saving throw made before the end of its next turn.

Lair & Regional Effects

If Beomeo chooses to remain in a pool or spring for 30 consecutive days, the site becomes a sacred locus:

The water never stagnates, remaining crystal clear and pure.

Within 1 mile, crops grow abundantly and creatures can’t suffer mundane disease.

Lore

A heavenly fish with a golden body, often depicted amid five-colored skies.

Beomeo is not a monster or yokai in the usual sense; its nature is entirely non-aggressive. It belongs to the class of sinsu (신수)—sacred animals that bridge the divine and human realms—or to the category of seojo (서조), heavenly omens of good fortune. Its appearance is regarded as a sign of great luck, a direct message from higher powers that the current order is blessed—or that a new era of prosperity is about to begin.

Beomeo’s true home is the heavens, where it dwells amid five-colored clouds—symbols of the Five Elements (fire, water, wood, metal, earth) and the five cardinal directions. It descends to earth only to swim and play in the purest waters: clear springs, deep pools, mountain lakes, and waterfalls.
