Traits

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

Omnipotent Awareness. The avatar cannot be surprised. It perceives events affecting cosmic Balance or divine law miles before they occur.

Divine Sovereignty. The avatar instantly recognizes divine beings, their portfolios, and any claim to ascension. Its attacks ignore the damage resistances and immunities of deities and divine avatars.

Aura of Absolute Order. Hostile creatures within 120 feet have disadvantage on saving throws. A creature that starts its turn in the aura must succeed on a DC 28 Wisdom saving throw or become incapacitated and forced to kneel until the start of its next turn.

Immutable Form. The avatar is immune to any effect that would alter its form or move it against its will.

Innate Spellcasting. Charisma is the avatar’s spellcasting ability (spell save DC 28, +18 to hit with spell attacks). It requires no components, and dead-magic or wild-magic zones do not affect this spellcasting.

At will: detect magic, dimension door, dispel magic, misty step, plane shift, scrying, teleport, true seeing
3/day each: foresight, meteor swarm, power word kill, shapechange, time stop
2/day each: divine word, gate, imprisonment, mind blank, true polymorph, true resurrection
1/day each: blade of disaster, psychic scream

Magic Resistance. The avatar has advantage on saving throws against spells and other magical effects.

Actions

Multiattack. The avatar makes four Hand of Judgment attacks.

Hand of Judgment. Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 45 (6d6 + 10) force damage plus 45 (6d6 + 10) radiant damage. A deity or creature with divine ranks must succeed on a DC 28 Constitution saving throw or lose its divine abilities until the end of its next turn.

Divine Arbiter. The avatar targets one divine creature it can see within 120 feet. The target must succeed on a DC 28 Charisma saving throw or lose access to its divine portfolio features for 1 minute. The target repeats the save at the end of each of its turns, ending the effect on a success.

Supreme Command (Recharge 5–6). The avatar summons one planar agent or construct of CR 25 or lower in an unoccupied space within 60 feet. It acts immediately after the avatar and remains for 1 hour, until destroyed, or until dismissed.

Reactions

Correct the Outcome. When a creature within 120 feet rolls a d20, the avatar replaces the roll with a 10 before modifiers.

Legendary Actions

The avatar can take 3 legendary actions, choosing from the options below. It regains spent legendary actions at the start of its turn.

Enforce Balance. One creature within 60 feet must succeed on a DC 28 Charisma saving throw or have its highest and lowest ability scores exchanged until the end of its next turn.

Cast Spell (Costs 2 Actions). The avatar casts a spell available through Innate Spellcasting.

Divine Sentence (Costs 3 Actions). One creature the avatar can see within 120 feet makes a DC 28 Charisma saving throw. On a failure, a mortal drops to 0 hit points. A divine avatar is banished to its home plane and cannot return for 24 hours.

Lair Actions

On initiative count 20 (losing initiative ties), the avatar uses one lair action. It cannot use the same option two rounds in a row.

Enforce Equilibrium. Each chosen creature within 120 feet must succeed on a DC 28 Wisdom saving throw or be polymorphed into a harmless form embodying cosmic neutrality until initiative count 20 on the next round.

Cosmic Cycle. Each creature within 120 feet makes a DC 28 Constitution saving throw, taking 63 (18d6) necrotic damage on a failure, or half as much on a success. A creature reduced to 0 hit points enters suspended animation and returns to 1 hit point after 1 minute.

Divine Severance. Each creature within 120 feet that channels divine magic must succeed on a DC 28 Charisma saving throw or be unable to cast divine spells or use deity-granted features until initiative count 20 on the next round.

Planar Shunting. Each chosen creature within 120 feet must succeed on a DC 28 Dexterity saving throw or shift into the Deep Ethereal until initiative count 20 on the next round.

Mythic Actions

The avatar can take 3 mythic actions per day, using one option at a time. It regains spent uses at dawn.

Cosmic Equilibrium. The avatar ends any number of conditions and other ongoing harmful effects on creatures it chooses within 240 feet.

Gift of Life. The avatar restores one dead creature to life as if by true resurrection, without components or a time limit.

Alter Reality. The avatar duplicates any spell of 9th level or lower without components. A non-instantaneous effect can be made permanent.

Divine Arbitrament (Costs 2 Actions). For 1 hour, the avatar establishes one law within 1 mile: a school of magic fails for all other creatures, gravity changes direction, or time moves at half or double speed.

Architect of Realmspace (Costs 2 Actions). The avatar permanently reshapes terrain and non-artifact structures within 1,000 feet.

Introduction

Ao is the Over-Power of Realmspace, a being outside the standard hierarchy of greater, intermediate, and lesser deities. The gods themselves answer to him. He regulates divine portfolios, recognizes ascensions, and decides which foreign powers may establish worship on Toril.

He requires no mortal worship, grants no spells, and remains indifferent to prayer. His concern is structural: the preservation of cosmic Balance and the duties attached to divine power. His appearance on the Material Plane therefore signals failure on a scale larger than kingdoms.

Physical Appearance

Ao manifests as a twelve-foot-tall human figure wrapped in black cloth stitched with stars and moons. His face is ageless, symmetrical, and almost without distinguishing features. The form resembles a judgment given a body rather than a person.

His eyes do not blaze. They observe. Sound, gravity, and distance seem to defer to him, and his voice may arrive as a private whisper or fill the entire sky.

Roleplaying the Avatar

Play Ao as detached, impersonal, and uninterested in negotiation. He does not debate his authority or explain more than a judgment requires.

Use short statements that describe what is now true.
Treat mortal urgency as irrelevant unless it affects divine law or cosmic Balance.
Never gloat. Punishment is administration, not revenge.
Let the environment carry his emphasis: wind stops, distant bells sound, or every shadow points the same way.

Use in a Campaign

End of an Era

Use the avatar during the collapse of a pantheon, a theft of divine portfolios, or an attempt to unmake the rules that constrain gods.

Final Arbiter

Ao may deny an ascension, recognize a new deity, strip a negligent god of power, or force divine rivals into a settlement.

Impossible Audience

A campaign can focus on earning a few moments of Ao’s attention. The challenge is proving that a mortal crisis threatens cosmic order rather than merely mortal lives.

Consequences of Defeat

Destroying the vessel cannot kill Ao. It can rupture local divine order, leave portfolios temporarily ungoverned, or invite a replacement judgment with fewer restraints.

Lairs

Ao has no permanent mortal lair. Any place where he manifests temporarily becomes a tribunal in which the ordinary rules of magic and divinity yield to his decree.

The Pavilion of Cynosure

A secluded demiplane where Faerûnian powers broker agreements under restrictions only Ao can impose.

The Astral Graveyard

A field of petrified divine husks that makes the cost of failed portfolios visible.

The Chamber of Existence

A Deep Ethereal vault of unrealized matter and time, suitable for reshaping the laws of a region.

The Silent Tribunal

An obsidian hall sealed from other divine senses. Only the avatar’s voice can be heard within it.
