Would the spell Disintegrate affect a carried creature?

During a recent D&D 5e session, a Retriever picked up a player character and started to move, using this ability:

If the paralyzed creature is Medium or smaller, the retriever can pick it up as part of the retriever’s move and walk or climb with it at full speed. (Mordenkainen’s Tome of Foes)

Another player character then cast Disintegrate on the Retriever. The text of disintegrate includes:

A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. A disintegrated creature and everything it is wearing and carrying, except magic items, are reduced to a pile of fine gray dust. (Basic Rules, pg. 233)

If the Retriever was successfully disintegrated, would the character being carried also be disintegrated?

Should we think of 5e’s greatsword as an especially beefy longsword, still able to be carried at the hip?

Historically, greatswords were so long they were impossible to carry at your hip, so you typically carried one around with it resting, point-up, against your shoulder. One benefit justifying this inconvenience was their reach. However, in 5e, greatswords are not “reach” weapons. Should we therefore think of the 5e greatsword as just an especially beefy longword–twice as heavy, but still short enough to be carried at the hip? Or, since we’re telling fantastical stories about fictional epic heroes, do we simply buy into the Hollywood back sheath, no matter how unreasonable that’s been shown to be in real life?

Bonus Question: Does your same answer apply to 5e’s other heavy and 2-handed but non-reach melee weapons, the maul and battleaxe?

Does the limitation on the Cave Fisher’s Filament action include the weight of carried equipment?

The Cave Fisher from Volo’s Guide to Monsters (pg. 130) has an action called Filament which says:

One creature grappled by the cave fisher’s adhesive filament must make a DC 13 Strength saving throw, provided that the target weighs 200 pounds or less. On a failure, the target is pulled into an unoccupied space within 5 feet of the cave fisher, and the cave fisher makes a claw attack against it as a bonus action.

Emphasis mine. I imagine its pretty uncommon for a medium sized PC’s bodyweight and carried equipment combine for a weight under 200 lbs. Does the Cave Fisher’s attack limitation include the weight of carried equipment?

data carried during TCP control flow

I am learning about TCP control flow and came across a question about how much data is carried by the 4th segment. The answer is supposed to be 1200 (2230 – 1030) but I don’t quite understand why.

By definition, I know that the acknowledgement number is telling the other side what is next expected from it. Thus 5 is the server acknowledging everything up to 2230 and telling the client that the server is expecting 2230 next, while 3 is the client acknowledging everything up to 3848 and telling the server that it next expects 3848. But I still don’t understand why we’re considering segment 5 and segment 2? If it’s only “expecting” then how do we know how much data is being carried?

Where is a grappled and carried creature placed when the grappler stops moving?

The Grappled condition states (from the point of view of the grappler):

Moving a Grappled Creature: When you move, you can drag or carry the Grappled creature with you, but your speed is halved, unless the creature is two or more sizes smaller than you.

I have no issue with the dragging portion of moving with a grappled creature but when carrying the creature where does it find itself on the end of your turn?

Can the grappling PC place the carried target down into whichever square in range they choose?

I have some issues with that, namely the ability to pass the grappled creature into a hazard with no difficulty. Imagine moving to the edge of a cliff and simply holding the grappled creature over the edge and then releasing the grapple. It seems too simple.

Other options include holding them in a fire, dropping them into a known trap, etc or simply stating that you’ve lifted the grappled creature over your head and placed them down on the other side of you so your allies can attack it.

None of seems right to me but I find anything to explicitly state how to handle carrying a grappled creature.

Must the Artillerist Artificer’s Tiny Eldritch Cannon be carried in their hand?

The Artillerist Artificer has the ability to make Eldritch Cannon(s). The rules for the cannon state that you can make two different sized versions of it:

you can take an action to magically create a Small or Tiny eldritch cannon in an unoccupied space on a horizontal surface within 5 reet of you. A Small eldritch cannon occupies its space, and a Tiny one can be held in one hand.

The wording is a little vague. Do the rules mean that the tiny version:

  1. Doesn’t occupy a space, therefore must be held in the artificer’s hand
  2. Can be held in one hand, unlike the small version, but otherwise functions like the small version with regard to space and movement if it is not.

Can the object created by Minor Illusion be carried or worn?

Looking at the RAW for Minor Illusion (PHB, page 260) and other questions, I recognize that Minor Illusion is very limited in its ability to move on its own or change its appearance. However, I’m wondering if the illusory object can be carried or worn as demonstrated in two examples:

  1. I want to convince a visiting noble that I’m the ruler of this small town, so before I meet him in the city center, I cast Minor Illusion to create a crown on my head. Assuming he doesn’t investigate (or fails) does it continue to sit naturally upon my head through normal movements?

  2. I’ve just stolen a historical battleaxe and the guard have been alerted to its absence. Can I choose someone who is rapidly walking away and cast an illusory version of the battleaxe strapped to his back as a diversion? Does this usage work until the illusion is investigated or interacted with (as normal.)

Can the Artificer Artillerist’s tiny-sized Eldritch Cannon that is not held in hand still ride or be carried elsewhere on the body?

As an Artillersit Artificer, if I create a tiny-sized Eldritch Cannon with legs, can I place this cannon somewhere on my person and let it use its legs to hold on to my character (on my head, shoulder (Predator!), wrist, belt, top of my backpack, etc.)?

I understand that with RAW, it cannot move on its own into an occupied space, so it would not be able to climb up onto me, but I think that I should still be able to pick it up and place it somewhere as an object interaction. It could use its legs to hold on once in place. If I can control it from up to 60 feet away, I would think that it shouldn’t hinder the use of my hands for other actions once it is there.

Do magic objects carried by a character keep working when unconscious?

We have lost a character in a battle in a strange way. He was wearing the:

Slippers of Spider Climbing
Wondrous item, uncommon (requires attunement)

While you wear these light shoes, you can move up, down and across vertical surfaces and upside down along ceilings, while leaving your hands free. You have a climbing speed equal to your walking speed. However, the slippers don´t allow you to move this way on a slippery surfaces such as one covered by ice or oil.

and he was struck down to 0 HP while standing on a wall, over a well.

Would he fall into the well and drown? Or would he remain unconscious hanging by his boots?

Is there any difference between objects that require attunement and those that don’t?

With the Blink spell, can a creature be carried into the ethereal plane? [duplicate]

This question already has an answer here:

  • What happens if I Blink while my Familiar sits on my shoulder? 1 answer

Consider a 5th level chain pact archfey Warlock named Tasmir.

Tasmir casts find familiar creating an imp named Molo. Molo shapechanges into raven form.

Tasmir carries Molo in his cloak and casts Blink.

At the end of Tasmir’s turn he disappears into the ethereal plane. Molo flies out of Tasmirs cloak.

Tasmir blinks back into the material plane leaving Molo behind in the ethereal fog.

Is this scenario reasonable?
