Magic Mouth

A waiting enchantment hidden in stone, wood, or iron speaks at exactly the wrong moment for whoever has crossed the line.

2nd-Level Illusion
Casting Time: 1 minute
Range: 30 feet
Components: V, S, M (a small bit of honeycomb and jade dust worth at least 10 gp, consumed by the spell)
Duration: Until dispelled
Available To: Bard, Sorcerer, Wizard

Effect: You implant a message in an object within range, choosing a visible or audible condition that will trigger it within 30 feet of the object. When that condition occurs, the object delivers the message you recorded, which can be up to 25 words long and spoken at the volume you choose. You may also cause a magical mouth to appear on the object while it speaks. The effect can be shaped to seem solemn, comic, threatening, ceremonial, eerie, or otherwise fitting to the object and message. The spell remains until dispelled.

Overview

Magic Mouth is a spell of preparation rather than force. It does not stop intruders by itself, but it changes how a place behaves when someone enters it. A sealed chamber can announce judgment. A gate can proclaim law. A treasure chest can threaten thieves. A shrine idol can speak only when taboo is broken. A hidden vault can greet the rightful heir and denounce everyone else.

That gives the spell unusual value. Mechanically, it is simple. In play, it is versatile. It can warn, bluff, delay, misdirect, reveal lore, reinforce ritual, or turn an ordinary room into a memorable scene. Few low-level spells do more to make architecture feel inhabited, defended, sacred, or haunted.

Because the spell lasts until dispelled, it also suits worldbuilding exceptionally well. Old ruins, noble tombs, wizard towers, treasure vaults, shrines, archives, and cursed houses all become more vivid when something inside them has been waiting to speak for years.

Uses

Warning wards. Place the spell on gates, doors, reliquaries, coffers, boundary stones, tomb lids, or hidden passages so trespass triggers a clear spoken warning.

Ceremonial voices. Use it in shrines, courts, halls, and tombs where statues, carved faces, masks, and sacred objects deliver ritual phrases, prayers, laws, titles, or condemnations.

False confidence or intimidation. A chest can claim to be cursed. A door can announce that guards are coming. An idol can declare judgment. Even without direct force, the right words at the right moment can change behaviour.

Delayed information. Instructions, passwords, confessions, threats, prophecies, and clues can be left in a place to be heard only under the proper conditions.

Dungeon personality. Magic Mouth is one of the best spells for making a location memorable. Players may forget a locked door. They rarely forget the door that spoke to them.

Tactics

Magic Mouth works best when attached to an object people are likely to notice, touch, open, disturb, or approach. Doors, locks, tombs, lecterns, idols, mirrors, reliquaries, chests, banners, and stone faces are usually stronger choices than random surfaces.

Its strength depends on trigger discipline. The better the trigger, the better the spell. Good triggers are clear, physical, and tied to the location: footsteps crossing a threshold, a chest being opened, a name being spoken, torchlight entering a chamber, someone touching a relic, or a creature approaching within a set distance.

The message itself should be brief and purposeful. With only 25 words, the spell is strongest when it warns, commands, accuses, identifies, threatens, or declares. It loses force when it rambles.

It is also best used in layers. Magic Mouth becomes far more effective when paired with real defenses, social consequences, or emotional pressure. A speaking warning before a trap is more memorable than a trap alone. A false reassurance before danger is crueler than silence. A sacred denunciation before a sealed shrine door can do more than a lock to make intruders hesitate.

Trigger and Message Examples

These are the kinds of uses that make the spell come alive at the table:

Threshold warning:
Trigger: when anyone other than the caster crosses the doorway.
Message: “Turn back now. This vault is sealed by oath and death.”

Tomb curse declaration:
Trigger: when the sarcophagus lid is touched.
Message: “You have disturbed the king. Leave your breath behind you.”

False bluff on a chest:
Trigger: when the lid is opened.
Message: “Poison released. Pray your gods were listening.”

Temple challenge:
Trigger: when someone speaks above a whisper before the altar.
Message: “Kneel, or be judged as one who enters without reverence.”

Hidden clue:
Trigger: when moonlight falls on the statue’s face.
Message: “Beneath the third stone waits the road below.”

Good Combinations

Alarm: Alarm detects intrusion; Magic Mouth gives it voice. Together they create a warning system that both senses and announces.

Arcane Lock: Arcane Lock bars entry, while Magic Mouth turns attempted entry into a scene of accusation, threat, or ritual challenge.

Hold Portal: A magically sealed threshold becomes much more dramatic when it also speaks commands, denunciations, or warnings at the moment of pressure.

Glyph of Warding: Magic Mouth can warn before the punishment lands, or falsely reassure intruders moments before the glyph triggers.

Illusory Script: One conceals meaning in writing; the other delivers meaning aloud under the right condition.

Nystul’s Magic Aura: Useful for making a prepared warded object seem harmless until it suddenly speaks.

Unseen Servant: Combined with speaking objects, this can make a house, crypt, shrine, or laboratory feel disturbingly alive.

DM Notes

Magic Mouth is easy to underestimate because it does not look dramatic on the spell list. In practice, it is one of the most useful spells for atmosphere, environmental storytelling, and prepared magical spaces.

Its best use is not as raw utility, but as a way of giving a place intention. A chamber that speaks feels different from a chamber that merely contains danger. A tomb that accuses the intruders feels older, prouder, and more personal. A shrine that warns in a calm voice can feel holier than one guarded by visible force.

When ruling on the spell, keep triggers grounded in visible or audible conditions within the spell’s range. Reward clever, careful phrasing, but do not let the spell become an all-knowing sensor. Its power lies in persistence, timing, and presentation.

For published adventures, this spell is one of the cleanest ways to deliver lore without pausing play. A speaking idol, a warning seal, a funerary mask, or a carved lintel can reveal history, law, taboo, identity, or threat exactly when the players are most ready to listen.

The message, which must be twenty-five or fewer words long, can be in any language known by you and can be delivered over a period of 10 minutes. The mouth cannot utter verbal components, use command words, or activate magical effects. It does, however, move according to the words articulated; if it were placed upon a statue, the mouth of the statue would move and appear to speak. Of course, magic mouth can be placed upon a tree, rock, or any other object or creature.

The spell functions when specific conditions are fulfilled according to your command as set in the spell. Commands can be as general or as detailed as desired, although only visual and audible triggers can be used. Triggers react to what appears to be the case. Disguises and illusions can fool them. Normal darkness does not defeat a visual trigger, but magical darkness or invisibility does. Silent movement or magical silence defeats audible triggers. Audible triggers can be keyed to general types of noises or to a specific noise or spoken word. Actions can serve as triggers if they are visible or audible. A magic mouth cannot distinguish alignment, level, Hit Dice, or class except by external garb.

The range limit of a trigger is 15 feet per caster level, so a 6th-level caster can command a magic mouth to respond to triggers as far as 90 feet away. Regardless of range, the mouth can respond only to visible or audible triggers and actions in line of sight or within hearing distance.

Magic mouth can be made permanent with a permanency spell.
