What happens when you break an object made by True Polymorph?

Is there an official ruling on what happens when an object made by True Polymorph is broken?

Situation:

True Polymorph is cast on a Human, turning them into a Twig.
An hour passes, making the effect permanent.
The Twig is snapped in half.

Does the Twig revert to the Human it was before the spell?
Does it take overflow object damage?
Does it remain a Twig, just broken?
Does dispelling part of the broken Twig dispel the entire True Polymorph?

Are their official rulings on any of the above? If so, what are they?

Polymorph Question :: Excess Damage (And resistances)

Ok so if I polymorph a Fire Giant into a Baby Chicken and drop it into Lava the Baby Chicken will take 10d10 or 18d10 if I dunk it.

When it hits 0 it reverts back to its previous form and takes the excess damage, but what if the creature was immune.. like a fire giant? Does it assume to take all that damage because it was a Baby Chicken? Basically Im tryin to turn a giant into a nugget.

If you cast True Polymorph on matter made with the Creation spell will the creature disappear after the duration of Creation ends?

Cast creation to make vegetables that last a day, then cast true polymorph to make a dwarf from the vegetables, does the Creature disappear after a day? It says that if you use the matter created by Creation as a component the spell fails but True Polymorph doesn’t use the target as a component.

Would detect magic recognize a creature or object affected by true polymorph?

Straightforward issue here: in the D&D 5e version of True Polymorph, the creature or object becomes permanently polymorphed into the creature or object of the caster’s choice after an hour has passed. Down the line, if a caster used the detect magic spell and examined the newly transformed creature or object, would they be able to detect magic?

In other words, if a wizard transformed an adventurer into a spoon with true polymorph, waited 61 minutes and tossed the spoon into a drawer full of perfectly normal spoons, would one of the party members then be able to use detect magic to determine which of these spoons is their party member?

How do multiple castings of True Polymorph interact?

When targeting a creature changed by any form of polymorph affect (Polymorph, Shapechange, Wild Shape, or True Polymorph), do you target the original creature, or the creature in its current form?

Some examples are called for to make this understandable.

A fighter has True Polymorph cast on him, changing him into a dragon. When a second wizard targets the fighter/dragon entity with another True Polymorph, turning him into an owlbear, what is the second wizard’s actual target? The dragon, which is the current form, or the fighter, which was the original form?

The behavior I’m most interested in is the result of one spell failing. In the above case, if the first wizard loses concentration, that True Polymorph ends. Per the spell description, the fighter should return to being a fighter. However, the second spell is still active, making him an owlbear.

  • If the second spell targeted the fighter, this spell should remain, and the fighter will remain in owlbear form despite the first wizard losing concentration.
  • However, if the target of the second casting was the dragon, it should fail, as the target (the dragon) no longer exists.
  • This interaction goes both ways: if the second wizard loses concentration, if he targeted the fighter, then the owlbear becomes a fighter. If he targeted the dragon, then the owlbear becomes a dragon.
  • What causes the spells to fail actually doesn’t matter. I’ve presented it as concentration loss for simplicity.

Answering the above situation will handle most cases of this problem, but we have to consider some additional cases with True Polymorph permanency.

  • If the second casting targets the fighter, not the dragon, would this instead target the dragon if the original True Polymorph spell was made permanent before the second casting took place?
  • If the second casting targets the fighter, not the dragon, and after the second True Polymorph is cast the first True Polymorph becomes permanent, does this end the effect of the second casting (since its target no longer exists, as the fighter is now permanently a dragon)?

EDIT: The original form of this question used damage as the means by which the spells ended in my examples, causing confusion with permanency which was not intended. My sincerest apologies for such a drastic change after answer(s) were submitted. The revised question should address all cases of damage as a means of ending a polymorph-style spell, except the case of True Polymorph’s permanent effect; that requires and answer to the linked question and is outside this question’s scope.

Can multiple casts of True Polymorph stack?

Heavily related to this question, I want to know if multiple castings of True Polymorph would stack if made permanent.

Picture this scenario: (Assume a willing target.) Any given character is TP’d into a T-Rex, whoever cast the spell maintains concentration long enough for the spell to become permanent. Either they or another character then cast the spell again targeting the T-Rex, TP’ing it into another creature, such as a giant ape. The second cast is also made permanent.

In the given scenario are there multiple layers now? If you were to dispel the TP on the giant ape would it then turn into a T-Rex or back into its original form? If it turns back into a T-Rex would this mean you could theoretically stack layers of TP ad infinitum?

This question is distinct from the linked question as that one seems to be asking about non-permanent instances of the spell.

What are the advantages of taking “Sculptor of Flesh” eldritch invocation over taking Polymorph as a spell?

I think I misunderstand how the eldritch invocations that grant spells “using a warlock spell slot”.

Sculptor of Flesh Prerequisite: 7th level

You can cast Polymorph once using a Warlock spell slot. You can’t do so again until you finish a Long Rest.

Looking at the Warlock spell list, you are also able to take Polymorph as a spell at 7th level. If I took Polymorph as a spell, couldn’t I cast it using pact slots every short rest? What is the point of using this as one of my eldritch invocations?

Are unwilling Changelings now immune to the Polymorph spell if using the stat block in Eberron: Rising from the Last War?

In the original question Are Changelings immune to the Polymorph spell?, it was decided that because Changelings didn’t have the Shapeshifter trait (though the answer should have said Shapechanger) Polymorph would still work on them. Now, with the release of Eberron: Rising from the Last War, Changelings have the following trait:

Shapechanger. As an action, you can change your appearance and your voice. You determine the specifics of the changes, including your coloration, hair length, and sex. You can also adjust your height and weight, but not so much that your size changes. You can make yourself appear as a member of another race, though none of your game statistics change. You can’t duplicate the appearance of a creature you’ve never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. Your clothing and equipment aren’t changed by this trait. You stay in this new form until you use an action to revert to your true form or until you die.

And with Polymorph’s description:

This spell transforms a creature that you can see within range into a new form. An unwilling creature must make a Wisdom saving throw to avoid the effect. The spell has no effect on a shapechanger or a creature with 0 hit points.

With Changelings actually having this trait, do they automatically pass Polymorph’s saving throw and remain unaffected? This only pertaining to unwilling Changelings, of course.

Can I true polymorph into an Ancient Brass Dragon, and then use its Change Shape ability?

If I were to cast True Polymorph (which permits all creatures, not just beasts, as the regular Polymorph does) on myself to turn myself into, say, an Ancient Brass Dragon (provided that I’m level 20, which is required due that dragon’s CR) – could I then use the Change Shape “racial” feature of the dragon?

Change Shape. The dragon magically polymorphs into a humanoid or beast that has a challenge rating no higher than its own, or back into its true form…

True Polymorph:

Choose one creature […] that you can see within range. You transform the creature into a different creature, […]. The transformation lasts for the duration, or until the target drops to 0 hit points or dies. If you concentrate on this spell for the full duration, the transformation becomes permanent.
Shapechangers aren’t affected by this spell. […].

Creature into Creature
[…] The target’s game statistics, including mental ability scores, are replaced by the statistics of the new form. It retains its alignment and personality. […]

I can’t find anything in the spell that would prevent one from doing so. The only thing that might come into play is the phrase “Shapechangers aren’t affected by this spell”. You as the caster are not a shapechanger, however, so even though you transform into a shapechanger, you aren’t when you cast the spell.

Can you get infinite spells through True Polymorph and Shapechange

So, let’s say you’re a level 17+ Wizard and you cast True Polymorph on yourself to turn yourself into a CR 17 Adult Gold Dragon. This grants you the stat block of said Adult Gold Dragon, granting you the statblock of said Gold Dragon, including its Shapechange ability, allowing it to assume the form of “a humanoid or beast with a Challenge Rating no higher than its own”. It uses this ability to turn into a CR 12 Archmage, which has the Spellcasting feature, allowing it to cast spells using as an 18th level spellcaster, using its intelligence score.

Once they expend a number of spell slots from its new form, it proceeds to use its new 9th-level spell slot to cast True Polymorph on itself again, turning into a brand new Adult Gold Dragon form, and then using Shapechange to turn into a brand new Archmage form, and then repeats this process to gain an infinite number of spell slots.

Is there anything that prevents this from working? I know that True Polymorph is a Concentration spell, so the first True Polymorph would end when they cast the second one, I don’t think they lose the spell they’re Concentrating on if they lose the Spellcasting feature that gave them the slot in the first place? 5e doesn’t have any hidden rules, and there doesn’t seem to be anything about it working that way in the Spellcasting chapter of the PHB – and if it did work that way, wouldn’t it break Polymorph spells in general, since they lose their Spellcasting class feature while Polymorphed?

Obviously the chain gets broken if they fail a Concentration saving throw, but they’d get the Adult Gold Dragon’s Legendary Resistance to help them out, there – and it’d get reset every time they True Polymorph themselves, too.
