Question on Damaging Animated Objects in 5e

This came up in a discussion with a fellow 5e DM:

A player casts Animate Object on 10 daggers. This makes 10 animated daggers with 20 HP and 18 AC according to the 5e PHB. Now according to the spell “When the animated object drops to 0 hit points, it reverts to its original object form, and any remaining damage carries over to its original object form.” This is all fine and good.

The 5e MM says something similar regarding animated objects: “An animated object reduced to 0 hit points becomes inanimate and is too damaged to be of much use or value to anyone.” Everything seems to agree.

Now, the DMG lists tables destructible objects. Daggers we presumed to be Tiny objects which according to the DMG would have 2 HP if fragile, and 5 HP if resilient. Under Object Armor Class it lists Iron/Steel with a 19 AC.

Here’s where the argument comes in:

According to the PHB, Animate Object changes the form of the object to a construct creature with 20 HP and 18 AC for Tiny objects. When it reaches 0 HP it reverts back to its original form (We’re assuming an object with 5 HP and 19 AC), with any excess damage carrying over to that original form.

So what happens when the daggers reach 0 HP taking into account the PHB, DMG, and MM?

Argument 1: When the animated dagger reaches 0 HP, it reverts back to a regular dagger with 5 HP (a la Wild Shape Druid feature), suggesting that it needs to take at least 25 damage to become unusable. The animated creature construct form is separate from the inanimate original form, therefore damage applied to the object in animated form is separate from damage applied to the object as a whole.

Argument 2: When the animated dagger reaches 0 HP, it becomes inanimate and is too damaged to be used, suggesting that it only needs 20 damage to become unusable (a la Shapechanger NPC feature). The animated creature construct form and the inanimate original form are still the same entity, therefore damage applied to the object in one form applies to the object as a whole rather than just to its animated nature.

So when or how do the daggers become so damaged that they’re unusable?

I’ve seen this answered for 3.5e and Pathfinder, but not for 5e and after hours of trying, unsuccessfully, to find a 5e answer, any insight in this would be appreciated 🙂

Can a rogue’s sneak attack feature be used on objects?

The Rogue’s Sneak Attack says

Beginning at 1st level, you know how to strike subtly and exploit a foe’s distraction. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon.

You don’t need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn’t incapacitated, and you don’t have disadvantage on the attack roll.

So my question is can it be used to deal extra damage to objects with normal HP.

Can the spell Arcane Lock be used on objects like books or backpacks?

Having recently had to endure a nosy little halfling, my wizard is considering going ham with Arcane Lock. The spell states that casting it locks

a closed door, window, gate, chest, or other entryway, and it becomes locked for the duration.

Obviously, neither a book nor a backpack are an ‘entryway’. There are plenty of books (many modern day diaries or journals, for example) that come with a locking cover, and it makes sense to me that this spell would affect the lock of such a book. But what about an item without a built-in locking mechanism?

The spell description refers to the target of the spell as an object on several occasions. Since a book is a closeable object, would Arcane Lock work to lock the book shut? How about a belt pouch, or backpack?

Can you leave objects behind in the ethereal plane?

After entering the ethereal plane through some means, is it possible to leave objects you brought with you behind, or do they always come back with you?

Does the answer depend on the means you used to enter the ethereal plane, or on the specific object you’re trying to leave behind?

Note: You only need to consider content published in official material when answering this question, but if the official material is completely silent on this matter interpretations are also fine.

Can Silent Image create multiple creatures or objects?

I am creating a second level Warlock and I was planning on taking the Misty Visions Invocation. This Invocation gives the ability to cast Silent Image at will. I have been doing a search online for uses of this spell and I constantly see posts on various websites saying to make X creatures doing whatever. I have seen nowhere a post saying it is not possible. I have found a question on here Does the Major Image spell allow the caster to fill the 20 ft cube with as many "body doubles" as he/she sees fit? asking about Major Image doing it and it was said it is not possible. That is a different spell and of a higher level. I would assume that it is not possible to create multiples in the 15ft cube but I can’t find anything stating that fact.

Can Silent Image create multiple creatures or objects in the space alloted to the spell on one casting?

Can multiple castings of Glyph of Warding be stored in different objects at the same time?

Glyph of Warding looks like it is going to be a very fun and useful spell once I learn it, but in its description I don’t see any mention of whether is can be cast multiple times to store spells in multiple objects. I’m guessing there is a verdict on this, does anyone know it?

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?

Does Locate Object work for objects on the ethereal plane?

The spell Etherealness reads in part:

You step into the border regions of the Ethereal Plane, in the area where it overlaps with your current plane. […] You can see and hear the plane you originated from, but everything there looks gray, and you can’t see anything more than 60 feet away.

While on the Ethereal Plane, you can only affect and be affected by other creatures on that plane. Creatures that aren’t on the Ethereal Plane can’t perceive you and can’t interact with you, unless a Special ability or magic has given them the ability to do so.

It’s not clear to me whether or not Locate Object satisfies the qualifications of the second paragraph.

By extension, it seems like this spell’s description includes a little general description about the ethereal plane. This would mean that the second paragraph applies both to the spell Etherealness and to creature abilities like Night Hag’s Etherealness.

In either case, does the spell Locate Object work to detect an object (carried by a creature using the spell or ability above) if that creature and object are located within 1,000 feet but on the ethereal plane?

How to set the Y position of Camera to another object’s y position, but only once, not continuously?

Essentially, I want to set the camera’s Y position to another GameObject’s Y position, but I only want to do this one. If you do

cam.transform.position = new Vector3(0, thing.transform.position.y, 0),

it will continuously update to that object’s y. Even if I store the Y float in a variable and set the camera’s y to that it still continuously updates. It is only supposed to happen once.
