Can the Telepathy spell convey enough information to qualify a location for Clairvoyance or Scrying?

Clairvoyance and Scrying are both useful spell for seeing a specific location:

You create an invisible sensor within range in a location familiar to you (a place you have visited or seen before) or in an obvious location that is unfamiliar to you (such as behind a door, around a corner, or in a grove of trees).


you can choose a location you have seen before as the target of [scrying]. When you do, the sensor appears at that location and doesn’t move.

If I want to create this sensor at a location I haven’t seen before in person, can I gain enough knowledge through telepathy to do so? Keep in mind that telepathy can share images:

Until the spell ends, you and the target can instantaneously share words, images, sounds, and other sensory messages with one another through the link…

…so I’m mostly wondering if images of a location are enough to qualify for clairvoyance and scrying‘s "seen before" requirement.

What happens when a Scrying target teleports away, or moves through a portal?

As the title says, I am unsure on the RAW or RAI of what would happen if a target who is being scried upon were to use the Teleport spell, or some other instant travel spell, for intraplanar only travel.

The relevant parts of Scrying:

You can see and hear a particular creature you choose that is on the same plane of existence as you.

On a failed save, the spell creates an Invisible sensor within 10 feet of the target.

The sensor moves with the target, remaining within 10 feet of it for the Duration.

If the target were to travel outside the plane, then they would cease being a valid target for the spell. However, if the target merely travels within the current plane, does the sensor teleport alongside them? Or does the spell simply end? Or some other effect I haven’t considered?

And is it different for spells where the target physically moves through a portal, vs just disappearing and reappearing? e.g. Arcane Gate vs Dimension Door.

Scrying on a creature with legendary resistance

My players recently decided that they would like to cast the Scry spell on a creature that has the Legendary Resistance trait.

Does this trait function outside of combat?

My major concern is that the creature wouldn’t necessarily know it was being scryed on in order to use the resistance to avoid it. In combat, a creature could see a (for example) fireball coming and decide to avoid it, but with no indicator at all that a spell was targeting the creature, it is less clear to me.

How to prevent scrying, Locate Person, teleportation, planeswalking, Locate City, and other intrusions in the name of national security [closed]

I am writing a story set in a modern world where D&D magic works. Now, I also have a Cheyenne Mountain like set of facilities in my world, underground hardened military airbases. Obviously, you don’t want any old bloke to be able to just use the Etherealness spell to waltz in through the walls and steal a nuclear warhead. You also don’t want the enemy war leader to be able to see inside your war room. And teleportation would really be a security disaster. Could the unit’s mages cast Mind Blank on every single one of the 570 staff of the base?

I had a couple ideas, using a multiple castings of or a homebrew larger version of the Forbiddance spell to cover every cubic foot of space inside the mountain and a similar method with Anti-Magic Field around the boundaries. This seems to block anything short of divine intervention, but I was thinking of asking you folks here about ideas as well. Would my idea work? Do you have any suggestions? Perhaps a magic item that could do the protection?

I’m not concerned as to which version the spell/item comes from.

Crystal ball and scrying

The Scrying spell has as its material component

A focus worth at least 1,000 gp, such as a crystal ball, a silver mirror, or a font filled with holy water

The magic item crystal ball says

While touching it, you can cast the Scrying spell (save DC 17) with it.

If using the magic crystal ball to cast scrying, you would not need to use the crystal ball itself as the focus and material component for the spell it allows you to cast, per DMG p. 141:

Some magic items allow the user to cast a spell from the item. The spell is cast at the lowest possible spell level, doesn’t expend any of the user’s spell slots, and requires no components, unless the item’s description says otherwise.

But suppose you actually knew the spell and could cast it yourself. If you did not have a silver mirror or holy water font, could you use a non-magic crystal ball as a material component?

That is, is the spell specifically asking for the magic item crystal ball, or is a non-magic ball of crystal, provided it is worth 1000gp, sufficient?

For reference, on the PHB adventuring gear list, an arcane focus "crystal" is worth 10gp, while an orb (with the same weight of the magic item crystal ball) is worth 20gp.

Should the target of Scrying know that they rolled a Saving Throw?

This is mainly a question about meta information, since players may act differently if they know that something happened requiring a saving throw. Especially if they know that a character will be casting scrying.

Would it be acceptable for a Dungeon Master to secretly roll a character’s save against the Scrying spell?

And (if so) do you think a player would feel cheated if their DM did that?

The spell doesn’t specifically address it, and I’m not aware of a rule that would apply here, so I would think that it would be up to DM discretion, but I would like to make sure.


What can be done to a Scrying sensor?

The spell Scrying states:

On a failed save, the spell creates an invisible sensor within 10 feet of the target. You can see and hear through the sensor as if you were there. The sensor moves with the target, remaining within 10 feet of it for the duration. A creature that can see invisible objects sees the sensor as a luminous orb about the size of your fist.

What can someone who is being scryed actually do to this sensor if they can see it? Can they destroy it? Dispel it? Or can they do nothing except gain the knowledge that they are under surveillance?

(Clairvoyance has identical wording, and Arcane Eye does something very similar, except it is an “eye” rather than a “sensor” – so it’s likely the answer would apply to these spells too.)

What is Jester using as a focus for Scrying in Critical Role?

Reading through the PHB, I found the spell Scrying, which has the following Components:

Components: V, S, M, (a focus worth at least 1000 gp, such as a crystal ball, a silver mirror or a font filled with holy water).

However, I never heard mention of such a focus in the show, even with Jester often Scrying in the wild. What object is she using?

5e: Does Blindsight detect a scrying sensor?

My party’s going to be encountering an Elder Oblex that’s gained more sentience than usual. The party has a mirror of Scrying (cast once per day without components/slots). They’re wanting to use said mirror to spy on the Oblex, get an idea where exactly it is, plan an ambush for it.

Elder Oblex has blindsight. Assuming the Oblex fails the save to resist the Scrying spell, would it notice the sensor created by the spell? The sensor is invisible, which would be ignored by the blindsight, but I’m not sure if the sensor does any other kind of sensory effect that could be detectable by blindsight.

The exact wording of Scrying is, “On a failed save, the spell creates an invisible sensor within 10 feet of the target. You can see and hear through the sensor as if you were there. The sensor moves with the target, remaining within 10 feet of it for the duration. A creature that can see invisible objects sees the sensor as a luminous orb about the size of your fist.”

Thanks in advance for any advice/insight!

Is it possible to attack enemies through a scrying sensor?

The Scrying spell allows players to look at distant targets. Are there abilities or spells that allow players or characters to launch attacks against a target they are scrying?

While I am aware that characters could teleport in, I’m more concerned about zero-risk attacks from super far away.

This question was spurred by the UA sorcerer ability, Hound of Ill Omen. Recently, one of my players cast Scrying on an commoner NPC from a great distance, and then used her Hound of Ill Omen feature on the NPC. The text of the feature reads,

As a bonus action, you can spend 3 sorcery points to summon a hound of ill omen to target one creature you can see. The hound uses a dire wolf’s statistics …

Because the character could see the NPC, I couldn’t find a good reason to disallow this, and the NPC was torn to pieces.

I’m not sure if this is just a quirk of the UA wording, or if there is a precedent for this kind of attack.

Just to be clear, my question is not whether Hound of Ill Omen works this way. My question is whether other abilities/spells/etc. also work this way.
