RAW, you cannot become invisible via moving fast
As the other answers have stated, there are no rules that imply this. When a monk reaches 18th level, they gain access to the Empty Body class feature (PHB, p. 79):
Beginning at 18th level, you can use your action to spend 4 ki points to become invisible for 1 minute. During that time, you also ...
They get lungs full of dust
The dust does what it says: if “you use an action to throw the dust into the air, you and each creature and object within 10 feet of you become Invisible for 2d4 minutes.”
If you don’t do that, you just have a pile of dust.
I told him no right off the bat...But he's extremely insistent about
Just tell the player "no," again; you are allowed to do that as DM
There are a number of reasons for this.
An invisible stalker is an elemental; PCs are humanoids1
The CR of an invisible stalker is 6; it usually takes 2 or 3 PCs of
level 6 to defeat an invisible stalker; the ...
Ask the player "why?"
First step to solving these types of issues is asking why they want a thing. If the character wants to be invisible all the time just for the sake of that, just say no. If they like the idea of being able to attack from being hidden or that type of thing then you can help them out.
The Gloomstalker Ranger is invisible in ...
No, you can't see the creature's aura, but you can detect if there's magic within 30 feet of you, including magic items he might be carrying, though you can't determine the nature of the items. From the text of Detect Magic:
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 ...
PHB p. 291 description of the Invisible condition states in part:
An invisible creature is impossible to see without the aid of magic or a special sense.
Blindsight is such a "special sense". (Other special senses that work against invisible creatures are Tremorsense and Truesight.)
The beneficiary of a nondetection spell:
Can’t be targeted by any divination magic, and
Can't be perceived through magical scrying sensors.
There are only two spells in the PHB that create magical scrying sensors: clairvoyance and scrying. These are obviously covered by Item 2.
It's reasonable to assume that the remaining 28 spells from the ...
These types of questions are pretty common. The rules are often unclear, IMO not necessarily because of inadequacies of the developers/writers, but because (as we see from the variety of answers/discussions) these are tough, complex questions. I don't have a definitive answer, but I have a recommendation that I believe warrants more than a comment, so I'll ...
Ok, crazy thing about the difference between hidden and invisible...there isn't much of one.
The big difference between the two is the ability to be attacked directly. If you are hidden, your enemy doesn't know your location, and thus cannot target you directly. They have to guess (DM should use some kind of randomization here), and may or may not actually ...
Yes, Nondetection does block the Trueseeing spell. This was addressed in a tweet by Crawford. It does beat True Seeing:
The nondetection spell hides you from divination magic. True seeing is a divination spell.

The Sorcerer can discriminate between invisible targets provided that they know the invisible targets are there
Once you are aware of an invisible creature, provided they are not hidden, you know where it is (because they are still making noise, kicking up dust, etc.) but you cannot, in general, see them.
If a spell specifies that you have to be able to ...
There is no such speed in D&D 5e. You will have to add it yourself.
There is no speed in D&D 5e that causes spontaneous invisibility.
Since you are deciding that there is such a speed, but D&D can’t tell you what it is, it’s up to you as the DM. You’ll have to pick a speed and create your own house rule that says, “a Speed of [whatever you ...
This will probably work
The Zone of Truth spell's text is fairly unambiguous on the knowledge gained by the caster (PHB p. 289, bold added):
Until the spell ends, a creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Charisma saving throw. [...] You know whether each creature succeeds or fails on its ...
The Special Sense Blindsense bypasses the mechanics of being Invisible
The Invisible condition states (emphasis mine):
An invisible creature is impossible to see without the aid of magic or a special sense.
Blindsight is a special type of sense, along with senses like True Sight and Tremorsense.
The condition explicitly calls out that there are special ...
According to lead rules designer Jeremy Crawford's unofficial ruling, attacks have advantage against invisible creatures affected by Faerie Fire. So your first interpretation aligns best with the intention of the spell.
A random roll for location is the best solution when an Out of Character player knows the location but has to "guess" in-game without that knowledge.
Given that, I'd like to discuss the times when there is and isn't a known location of a creature. The RAW regarding unseen attackers and hidden attackers is fairly clear, although it is also somewhat ...
Items you pick up become invisible if tucked into your clothing. If you wear a reversible cloak, you can reverse it after getting the outside covered in flour. The inside was not covered in flour, and so you are now invisible again.
If there are going to be multiple flour traps, you might need to carry several cloaks you can pull out of a pocket and drape ...
The additional end condition affects creatures separately
This is what
The spell ends for a target that attacks or casts a spell.
means. If this addendum was not there, it would mean that the spell, as a whole, ends. This limits the effect. Also, you can concentrate on spells that do not target or affect you, this case is no different.
Any carried object will be visible
Starting at 3rd level, when you cast Mage Hand, you can make the spectral hand invisible
"You can make the spectral hand invisible" does not mean "you can cast the Invisibility spell on it". It does what it says — you make the hand invisible, and only the hand, not the item it is carrying.
However, D&D 5th edition ...
You can ready one attack without breaking invisibility, but not a spell.
Readying an action allows you to use your action to act outside of your turn. This allows you to ready an attack action which you will execute later. Once you do execute it, you will have made an attack and will break invisibility. Note that it doesn't matter if you make your attack ...
From the description you included of Detect Magic:
...you can use your action to see a faint aura around any visible creature or object in the area that bears magic...
The Invisible Stalker is not a visible creature, and therefore not qualified to be outlined by the spell.
Relatedly, you would also not be able to sense the presence of its ...
No, being invisible does not grant advantage on stealth checks, RAW
I was going to present this in my question as evidence of what I'd already looked into, but then decided it was better off as an answer, attempting to assert the position that being invisible doesn't grant advantage on stealth, since that's what I concluded after looking into it. Here's what ...
"items picked up disappear if tucked into the clothing or pouches worn
by the creature."
– Invisibility, d20srd
Based on the above, I'd say stuff put into the box arguably becomes invisible. A pouch is a container. A box is a container. Stuff put into an invisible container disappear.
Sure, the RAW says in the quote above that the container is "worn by ...
No, Divine Sense won't allow you to hit it as if it was visible. Invisibility says that:
Attack rolls against the creature have disadvantage,
and the creature’s attack rolls have advantage.
and Divine Sense does nothing to change that. So what's the advantage of sensing them? Well, the advantage is that you sense them. If you use Divine Sense and ...
Your ruling is correct.
Your ruling is correct. Invisibility states the circumstances that end the condition. Receiving Damage does not end the condition.
Invisibility (PHB 243):
A creature you touch becomes invisible until the spell ends. Anything
the target is wearing or carrying is invisible as long as it is on
the target’s person. The spell ends ...
Knowing where an invisible creature is allows you to attack them at disadvantage.
There are two related questions, here and here explaining that if you are invisible that other creatures do still know where you are because they can still hear you. The "Unseen Attacks" section states:
When you attack a target that you can't see, you have ...
The light spell says:
Completely covering the object with something opaque blocks the light.
The amulet may not be visible, but it is not covered. Therefore, the light will still emit in a 20'radius around the amulet/bard.
Yes, advantage applies
Why? The you in the unseen attackers sections is referring to whatever creature is invisible / can't be seen. In this case it is your familiar, and it would have advantage even though it uses your attack modifier.
Can you dispel a magic effect you can't perceive?
Yes, as long as you can locate it somehow. If you can't find it somehow, then no. This reduces down to the related question: Can you target a target that you can't perceive? And the answer to that is a qualified yes. Yes, if you can land your dispel magic on the desired target somehow.
As we'll see, your ...
