What damaged a creature that is in an antimagic field from which it is excluded?

I read a lot about this topic, more precisely I base myself on what is stated here:

  • Does the feat Extraordinary Spell Aim affect the creature’s space or the creature? (and other linked discussion)
  • What happens when an anti magic field gets close to a polymorphed creature?

but about the Extraordinary Spell Aim + Anti magic field combo, I have not yet clear some points.

In all the following examples Jozan is a 15th level cleric with feat: Persistent Spell + Divine Metamagic applied to Persistent Spell + Extraordinary Spell Aim; and with anti-magic field from which he is excluded

As for the Extraordinary Spell Aim effect space, I agree with KRyan when he says that the PC is excluded from the spell’s area, not the square where the PC is.

For example, if Jozan takes Vadania (page 34, Player Handbook) close into a grapple, Mialee can cast a Fireball with the certainty of not doing damage to the druid. The spell has no effect on Vadania but takes Jozan because Jozan is excluded from the anti magical field, and not the square he occupies.

But what else damage Jozan?

  1. Do all spells targeting Jozan take effect? Does Magic Missile or Ray of Enfeeblement or Streamers do damage? What is the discriminate to understand which spell does damage and which doesn’t?

  2. Do the magic weapons used against Jozan and out of his anti-magic field have bonuses of some kind for hitting and/or doing damage? If Jozan is the target of an arrow, does he take damage if it is magical (for example if the arrow – and only this – is +1) or is fired by a magic bow (for example if the bow – and only this – is +1)? Does the archer have a bonus to hit roll, or to damage and to hit roll or to damage or to neither of the two?

  3. Do the magic weapons used against Jozan and in of his anti-magic field have bonuses of some kind for hitting and/or doing damage? If Jozan is the target of a Greatsword +1, would the enemy have advantages on his roll to hit or damage or both? If an Assassin attacks Jozan using Wraithstrike does this spell take effect when Jozan is attacked?

Can Detect Magic detect an Antimagic Field

This is a duplicate of this question, but for a different gaming system; Pathfinder v1 vs DnD 5e. Also relevant, but slightly different is this question about intersection.

So the gist is, a wizard is sitting in the middle of an empty 50’x50′ room. They have cast Antimagic Field on themselves (10′ radius so well within the confines of the room with no obstructions).

Another character opens the door and doesn’t trust the wizard with the wry smile and casts Detect Magic (30′ radius, so big enough to reach the wizard 25′ away but well outside the Antimagic Field).

Things within the Antimagic Field appear mundane, as per the spell description. But does the other character sense the abjuration spell itself?

Can I cure a Spawn of Kyuss in an Antimagic Field with Lesser Restoration?

If I cast lesser restoration on a Spawn of Kyuss, who is within an Antimagic Field (as per the spell), from outside the Antimagic Field, what happens?

A Spawn of Kyuss has the Worms trait which says:

If the Spawn of Kyuss is targeted by an effect that cures disease or removes a curse, all the worms infesting it wither away, and it loses its Burrowing Worm action.

I am targeting the Spawn of Kyuss with lesser restoration which would cause cure disease normally, but…

Targeted Effects: Spells and other magical effects … that target a creature or an object in the sphere have no effect on that target.

[from antimagic field]

Does the Worms trait trigger from this casting of lesser restoration?

I ask because the Worms trait only says it needs to be targeted by the disease-curing effect, not that it needs to be affected by it.

Would an anti-magic field block targets of Dragon’s Breath spell user?

Consider someone has dragon’s breath cast on them.

Until the spell ends, the creature can use an action to exhale energy of the chosen type in a 15-foot cone.

What happens if this creature exhale energy on targets inside an antimagic field?

Does the effect pass through as if it were a dragon’s breath weapon?

What capabilities does a Vampire have inside an anti-magic field

In a campaign I’ve been playing we recently stumbled upon a town (population of a couple of thousand) that was hidden via a large scale illusion spell, and shielded from the outside world, via a large Antimagic Field.

We were told by some of the populace that a friendly Vampire lived in town.

Which got me thinking, what are the capabilities of a Vampire living within an Antimagic Field?

Some are obvious, it cannot use its Children of the Night or Charm actions, as they are explicitly stated as magic.

But can it use Shapechanger or Spider Climb? Are the Vampire Weaknesses applicable in an Antimagic Field? Does it regenerate in an Antimagic Field?

Are these pretty much all up to the DM?

Does Antimagic Field suppress all layers of True Polymorph simultaneously?

Imagine that you have cast True Polymorph to turn a medium object into a Helmed Horror with Spell Immunity to Antimagic Field. If you were to then True Polymorph that Helmed Horror into something else, it would lose its Spell Immunity, as its entire statblock is changed. However, what exactly would happen if the newly True Polymorphed creature walked into an Antimagic Field?

I see two plausible outcomes:

  1. Both layers of True Polymorph are suppressed simultaneously and the creature is immediately turned back into a medium object.
  2. The most recent layer of True Polymorph is suppressed, at which point the Helmed Horror’s Spell Immunity kicks in and prevents the next layer from being suppressed.

I think each of these interpretations has a decent argument:

  1. This is how Dispel Magic works. If the Helmed Horror also had Spell Immunity to Dispel Magic, the underlying layer of True Polymorph could still be dispelled, because Dispel Magic reads (emphasis mine):

For each spell of 4th level or higher on the target, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a successful check, the spell ends.

Both layers of True Polymorph are on the target, and so both can be dispelled, and there is no reason to suspect they aren’t dispelled simultaneously (before the Spell Immunity could ever kick in).

  1. Antimagic Field reads (emphasis mine):

Any active spell or other magical effect on a creature or an object in the sphere is suppressed while the creature or object is in it.

And while there are two layers of True Polymorph on the creature, it seems reasonable to assume that only the most recent is “active”, due to the rules for Combining Magical Effects:

The effects of the same spell cast multiple times don’t combine, however. Instead, the most potent effect–such as the highest bonus–from those castings applies while their durations overlap, or the most recent effect applies if the castings are equally potent and their durations overlap.

This (plausibly, I think) could be interpreted to mean that the most recent layer of True Polymorph is suppressed first, at which point Antimagic Field would suppress the next layer if not for the Spell Immunity.

Is one of these two interpretations unambiguously supported by Rules as Written?

Would an anti-magic zone affect a dragon’s breath weapon?

One of my players has a special crystal that emits an anti-magic zone 5-feet around them. It was just picked up so they’re trying to figure out what to do with the crystal. Suddenly they are ambushed by a Green Dragon who opens with its Acid Breath. So the question is, would the crystal’s anti-magic zone negate the dragon’s breath?

Is a Dwarven Thrower’s Returning property affected by the Antimagic Field spell?

The antimagic field spell states:

[…] A magic weapon’s properties and powers are suppressed if it is used against a target in the sphere or wielded by an attacker in the sphere. If a magic weapon or a piece of magic ammunition fully leaves the sphere (for example, if you fire a magic arrow or throw a magic spear at a target outside the sphere), the magic of the item ceases to be suppressed as soon as it exits […]

However, the Dwarven thrower is a rather unusual weapon, it is magic and it states:

[…] Immediately after the attack, the weapon flies back to your hand […]

Say somebody is inside the sphere and they throw a Dwarven Thrower at an enemy who is outside the sphere. Presumably the hammer will leave the sphere, thus no longer being suppressed by the field. Then it hits its target and tries to return to the attacker. Eventually it will come back in contact with the sphere. What happens then? Does the antimagic field stop the Dwarven Thrower from returning all the way?

What can damage a lich in an antimagic field?

An antimagic field spell makes magical weapons into normal weapons for purposes of attack. Magical spells also lose their effects.

A lich is listed as having damage immunities to: Poison; Bludgeoning, Piercing, and Slashing From Nonmagical Attacks. Liches also have condition immunities to: Charmed, Exhaustion, Frightened, Paralyzed, and Poisoned.

The only effects that penetrate an antimagic field are artifacts and effects from deities. Given the immunities of a lich, this seems to leave only fire and acid as a way to damage liches apart from artifacts and deities.

However, Jeremy Crawford previously wrote, “Antimagic field has no effect on a creature’s immunities, unless those immunities are sustained by magic.”

Are a lich’s immunities “sustained by magic” as described by Crawford and go away in an antimagic field? More generally, apart from artifacts, deities, and fire, what can damage a lich in an antimagic field?
