If a creature is transformed into an object by the True Polymorph spell, what happens when you break that object?

Question

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

Situation:

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

What is the outcome?

• Does the Twig revert to the Human it was before the spell when snapped?
• Does dealing damage to the object apply remaining damage above the object's health to the Human, if or when it reverts?
• Does it remain a Twig, just broken in twain?
• Does dispelling part of the broken Twig dispel the entire True Polymorph?

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

Answer 1

Nothing special happens

• Does the Twig automatically revert when the twig is damaged? No, the spell doesn't say to do that.
• Is the Human the same as before the spell was cast? Yes, the spell says that creatures return to their normal form, there is nothing about carrying over damage.
• Does it take overflow object damage? Object damage is for attacking objects, snapping a twig is not an attack.
• Does it remain a Twig, just broken? Yes, you snapped the twig, so now you have a broken twig.
• Does dispelling part of the broken Twig dispel the entire True Polymorph? Yes, there is only 1 spell, so targeting either part will dispel the spell.
• Does damage to the object become damage to the creature? Nothing says that hurting the object hurts the target.
