Antimagic Field 5e: Suppression, Magic Items, and Limits

I’ve always found Antimagic Field fascinating because it changes the rules of the space around the caster instead of simply canceling one spell. Inside its moving sphere, enchanted weapons become ordinary, ongoing spells fall dormant, and summoned creatures can vanish temporarily. Its protection is powerful, but it suppresses friendly magic too and demands concentration from the person standing at its center.

Antimagic Field 5e — Quick Spell Reference

How Antimagic Field Works

An invisible 10-foot-radius sphere surrounds the caster and moves with them. Inside it, spells cannot be cast, magic items lose their magical properties, summoned creatures can disappear, and most other magical effects are suppressed. Effects created by an artifact or a deity are exceptions.

The caster is inside the sphere and receives no personal exemption from its suppression. Antimagic Field continues sustaining its own area as a specific exception, but the caster’s other magic is affected normally.

Suppression is not the same as dispelling. A suppressed effect stops functioning where the field applies, but its duration continues to run. It resumes after leaving the sphere or after Antimagic Field ends, provided its duration has not already expired.

For example, a creature affected by a 1-minute spell receives no benefit from that spell while inside the field. If it leaves after 3 rounds, the spell can resume, but those 3 rounds still counted against the duration.

Can Spells Be Cast Inside Antimagic Field?

No. The 2014 spell explicitly prevents spells from being cast inside its sphere. A creature can still take ordinary actions, attack with a mundane weapon, or use a feature that is not magical, but it cannot produce a spell from within the field.

A spell or magical effect also cannot affect a creature or object inside the sphere by targeting it from outside. An attempted Magic Missile, Charm Person, healing spell, or other targeted spell has no effect on a protected target. When a spell slot is expended on a spell whose effect is suppressed, the slot is still consumed.

The field is not total cover and does not stop ordinary attacks. An arrow, falling rock, breath weapon, or other nonmagical effect can cross its boundary normally unless another rule says otherwise.

What Happens When a Spell Area Overlaps the Field?

A magical area cannot extend into the sphere. If a Wall of Fire or another ongoing spell overlaps the field, the overlapping portion is suppressed while the rest continues to function. Moving the sphere can therefore create a temporary gap that moves with the caster.

The same principle applies to an instantaneous area spell aimed outside the sphere: the spell can affect creatures outside, but its magical area cannot protrude into the field. Antimagic Field does not reflect a spell, redirect it, or end the unaffected portions of an ongoing area.

How Antimagic Field Affects Magic Items and Weapons

The properties and powers of a magic item are suppressed while the item is inside the sphere. A +1 sword becomes an ordinary sword of the same type, magic armor loses its magical bonus, and an activated item power does not function there. The item is not damaged or permanently disenchanted; its properties return when it leaves the field.

A magic weapon’s properties are also suppressed when it is used against a target inside the sphere, even if its wielder stands outside. Conversely, a magical projectile that completely leaves the field before striking a target outside regains its magical properties as soon as it exits.

Only the magical properties are suppressed. A sword remains a sword, armor still provides its ordinary protection, and an item retains its physical shape and mundane functions.

Do Summoned and Created Creatures Disappear?

A creature or object summoned or created by ongoing magic temporarily winks out while it is inside the sphere. It immediately reappears when the space it occupied is no longer covered by the field. Its spell duration continues to expire while it is absent.

The important distinction is whether magic is still sustaining the result. Official 2014 Sage Advice explains that an instantaneous spell leaves no ongoing spell effect to suppress. An undead creature created by Animate Dead, for example, continues to exist in Antimagic Field because that spell’s magic has already ended. A creature maintained by a spell with a non-instantaneous duration, such as Conjure Woodland Beings, temporarily disappears.

This duration test also applies to other spell-created results. Something can have a magical origin without remaining an ongoing magical effect.

Does Antimagic Field Stop Teleportation and Portals?

Yes. Teleportation and planar travel fail when the sphere contains either the origin or the destination. A creature cannot teleport out of the field, and a creature outside cannot teleport into it.

Portals and extradimensional openings temporarily close wherever the sphere overlaps them. They reopen after the overlap ends if their own durations have not expired. Moving the field over a portal suppresses it; it does not normally destroy it.

What Counts as Magical?

Antimagic Field suppresses focused magical effects, not everything supernatural or extraordinary in the game. The official 2014 Sage Advice checklist treats a feature as magical if any of these questions has a yes answer:

• Is it a magic item?
• Is it a spell, or does it reproduce a named spell’s effect?
• Is it a spell attack?
• Is it fueled by spell slots?
• Does its description say it is magical?

Use the wording of the specific rules version being played. A class or monster feature is not automatically suppressed merely because its name or flavor sounds supernatural.

A typical dragon’s breath weapon is the official example: it is extraordinary, but it is not a spell, spell attack, magic item, spell-slot-powered feature, or described as magical. Antimagic Field therefore does not stop it. A feature that expressly creates a magical effect would be suppressed.

Does Entering the Field Break Concentration?

Entering an Antimagic Field does not, by itself, end concentration. The spell does not list antimagic as a reason concentration breaks. A creature inside can continue concentrating unless it takes damage, becomes incapacitated, starts another concentration spell, or encounters another normal cause of lost concentration.

The concentrated spell’s effect can still be suppressed. A target inside the field receives no benefit from a suppressed spell, and a magical area cannot extend into the sphere. If the relevant target or area later leaves, the spell can resume for whatever duration remains.

The Antimagic Field caster is already concentrating on this spell and therefore cannot simultaneously maintain another concentration spell. See the site’s concentration rules for the normal ways that concentration ends.

Can Anything Ignore or End Antimagic Field?

Dispel Magic has no effect on Antimagic Field, and two overlapping Antimagic Field spheres do not cancel each other. The field normally ends only when its caster loses concentration, dismisses concentration, or reaches the 1-hour limit.

Magic created by an artifact or a deity is exempt from the spell’s general suppression. Specific rules can also override Antimagic Field. Prismatic Wall, for example, expressly says that Antimagic Field has no effect on it. These are exceptions, not evidence that every high-level spell or legendary item ignores the sphere.

Antimagic Field: 2014 vs. 2024 Rules

The versions retain the same level, classes, 10-foot moving area, concentration, maximum duration, magic-item suppression, teleportation block, and immunity to Dispel Magic.

The material gameplay clarification is that the 2024 spell explicitly prevents creatures inside its aura from taking Magic actions or creating other magical effects. The 2014 version says spells cannot be cast and relies on the spell’s suppression rules plus the wording of each non-spell feature. This page’s main explanation and quick-reference table use the 2014 rules.

The 2024 description calls the area a 10-foot Emanation and shortens the material component to iron filings. Those terminology and component-wording changes do not otherwise alter the field’s central behavior.

Casting Antimagic Field at 9th Level

Antimagic Field has no higher-level benefit. A 9th-level slot does not increase the radius or duration, strengthen the suppression, or remove concentration. Unless an unusual circumstance requires the spell and no 8th-level slot is available, upcasting spends a scarcer slot for the same effect.

Tactical Uses and Tradeoffs

Antimagic Field can escort allies through hostile magical areas, neutralize magical barriers, close portals, suppress enemy equipment, and deny spellcasting in close quarters. Because the sphere follows the caster, positioning determines which creatures and effects are protected or disabled.

Its drawbacks are equally important. The field suppresses allied spells and items, prevents magical healing inside, occupies the caster’s concentration, and has only a 10-foot radius. The caster may need to move close to a dangerous enemy while relying on ordinary armor, weapons, and allies for protection.

The spell is strongest when the group plans around being temporarily mundane. It is much less attractive when the party depends on magical weapons, ongoing buffs, summoned allies, or short-range healing.

FAQ

Does Antimagic Field permanently remove magic?

No. It normally suppresses an effect rather than dispelling it. The effect returns when suppression ends if it still has duration remaining.

Can a spellcaster outside the field target someone inside it?

The spell can be attempted, but a spell or magical effect has no effect on a creature or object inside the sphere. An expended spell slot is still consumed.

Does Antimagic Field stop a dragon’s breath weapon?

Not a typical dragon’s breath. Official 2014 guidance treats it as an extraordinary but nonmagical feature, so the field does not suppress it.

Does healing disappear when a creature enters the field?

Hit points already restored by an instantaneous healing spell remain. The magic has ended, leaving no ongoing spell effect to suppress. An ongoing magical bonus or regeneration effect would be suppressed while its target is inside.

Can a magic weapon attack through the boundary?

Its magical properties do not apply against a target inside the sphere. If a magical projectile leaves the sphere and hits a target outside, its magic resumes after it crosses the boundary.
