* Can Rope Trick be detected by the Detect Magic spell? Specifically if the rope is pulled inside. I imagine at that stage the rope is wholly contained within the extradimensional space so no component is present on the material plane for a wizard to target. Is this the case or is it just invisible and an enemy with true sight could still the entrance and dispel it?

* What is the minimum length of rope required to cast the spell?

* Is someone taking a bag of holding into the rope trick dimension likely to trigger the effect of putting a bag of holding into another one?

* If all but one member of a party get into a rope trick pocket on a small length of rope, pulling it almost closed behind them, could that remaining character pocket the inch or so of rope remaining and basically carry the party while they move?

Rope Trick

The range on detect magic is 30 feet, it could only detect the extradimensional space if it is within range.

There is no minimum length of rope, only a maximum.

The rules for those interdimensional mishaps only applies if the one that the bag of holding is placed inside of is created by an object. So do not put your bag of holding inside another one, but taking it into the space created by rope trick should be fine.

No. I believe the space created is stationary.

I hope that was helpful

Thanks. If the dimensional pocket was detected, could it be dispelled while it was closed?

Dispel Magic

I believe so, yes.

Dispel Magic:

Choose one creature, object, or magical effect within range. Any spell of 3rd level or lower on the target ends. 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.

Hmm... it does say that attacks and spells can't cross through the entrance... and it is in another dimension...

...maybe an argument could be made that it can't be detected or even dispelled???

Might depend on the DM? Wouldn't you have to be directly under it and looking up to have any chance to detect it? And dispel magic requires a target... how do you target something that isn't even in this dimension?

Each DM may answer these questions differently.

 

The interior cannot be detected or dispelled but the entrance is detectable and dispellable. 

 I imagine that if the entrance is dispelled the whole thing is.

Also, I don't believe you can close the portal to Rope Trick, you can just pull up the rope so it's not noticeable.

 I sure hope it is... if you can dispel just the entrance that's basically trapping a bunch of people in an alternate dimension.

Good point... but it's also a potential guaranteed 60 foot drop for everyone involved

 Only if the rope was 60 feet long. If it was only 3 feet long not so much.

I would argue that since rope trick is cast on the rope. Only the rope should register for detect magic or be targetable by dispel magic. If the rope is within the extra dimensional space, it should be out of range of both those spells.

Detect magic might be able to detect the entrance, but could not tell location or school. See invisibility should probably see through the entrance (but not see full space). And dispel magic should only work on the rope, not the entrance.

My interpretation anyway.

I don't think there is any disagreement on other questions:

• No official minimum length, but I would make it 5 feet to be reasonable.
• Bags of holding and similar are not a problem.
• The entrance to the space is stationary.

 I would think the entrance should also register as magical for the purposes of detect magic as long as it’s within the 30 feet. I mean, how would the entrance to an extradimensional space not register as “a magical effect in the area?” It just is such an edge case since rope, hempen (50 feet) is what it is.

Well, detect magic does say it can detect magic but only on any visible creature or object... the entrance to rope trick is invisible.

This clearly means according to RAW that it can't be detected by detect magic.

Also, no attacks or spells can cross through the entrance... so I don't think it can be dispelled... or anything else for that matter.

This clearly means according to RAW that it can't be dispelled by dispel magic.

(at least it seems reasonable to rule that way?)

 Incorrect. The spell says that if you sense magic you can see an aura around visible objects. So you would not be able to tell any information other than “there is magic there”

For the duration, you sense the presence of magic within 30 feet of you. If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any.

The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.

Thread from last year, some good points about similar mechanics. "See Invisibility" should be required to dispel it.

So let's try this again... each time you post that detect magic can detect auras around visible objects... or highlight it to say the same thing, visible creature or object... what part of invisible entrance do you not get... if detect magic detects visible and the entrance is invisible... visible vs. invisible

I don't know how you do not pick up on this... visible and invisible... get it?

Detect magic cannot detect invisible things... the entrance to the rope trick is invisible.

(wait a minute, do you actually get this and are just trolling me or something... just curious)

 Okay, let’s try this again. It says:

For the duration, you sense the presence of magic within 30 feet of you. If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any.

Lets break this down:

For the duration, you sense the presence of magic within 30 feet of you.

That means it detects the presence of magic within 30 feet. It does not specify “visible.”

If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any.

That means If you have already sensed it, and it’s visible, then you can see the aura.

You can detect the presence of magic it if it’s visible, invisible, sitting on you face, whatever, as long as it is within 30 feet. You can only see it’s aura if it’s visible. The spell has two effects, one that requires nothing other than a 30-foot proximity, and the second effect requires the first effect, and visibility.

So, I will repeat, again, you could since the presence of the portal, but not be able to detect its location because it is invisible. Have I finally made that clear enough for you?

The first part of Detect Magic says that it detects the presence of magic without mentioning whether the source is visible or invisible. It's only the second part of the spell, the one that displays an aura based on the school of magic, that requires that a target be visible. So you can still detect the presence of invisible magical things with the spell, you just can't determine its school.

 Or see the aura that would indicate exact location. You get “presence of magic” but nothing more specific than that.  Otherwise, this^^^

Right, general presence but not exact location or school.

Quote from Brian_Avery >>

I have agreed with that from the beginning, most of the past posts have never made it clear that they were just detecting the presence of magic and not seeing the aura because it's invisible. Thanks for clarifying this to the point that you have actually been agreeing with me from the beginning.

Detect magic can detect the presence of magic, but not see any auras on invisible objects, so not know where the rope trick entrance is.

Now where do we stand on dispel magic affecting things in other dimensions (which is essentially another plane of existence)... I think you have to be on the same plane of existence for spells to interact... but not entirely sure on cross dimensional casting. Usually things that are on different planes of existence don't interact with each other.

 

 I would say that if the entrance is dispelled, the spell is dispelled.

I agree with this, but in the specific case of Rope Trick the portal is still present on this plane and could be dispelled if it can be located to be targeted.
