What happens if a wizard attempts to create a complex object made of many parts using the True Polymorph spell?
Let's say that a wizard tries to create a large ship/boat using True Polymorph. Now, a boat is made of a main wooden body and many other parts, more or less "removable" (e.g. sails, wheel, furniture, crates, ropes). Are they created along with the main body? Is it necessary to roll some kind of knowledge check to determine the result?
