Undoing the effects of Sculpt Corpse

[EightViolett]

So, let's say the player characters find a corpse and successfully figure out that it has been tampered with via the spell Sculpt Corpse.
Now, they want to know whose corpse it actually is.

1) Since the duration on Sculpt Corpse is 'instantaneous' and not 'permanent', it is not an 'ongoing spell' that could be targeted by Dispel Magic, right?

2) Restore Corpse has 'corpse touched' as its target, but in the description it specifies that the corpse has to be 'decomposed or skeletonized'. Would the spell still be able to restore the corpse, as in, to its original appearance, even if neither the original nor the current appearance are 'decomposed or skeletonized'?

3) In case Restore Corpse fails because of the 'decomposed or skeletonized' part, could you circumvent that by casting
Decompose Corpse, then Restore Corpse?

1: Correct, dispel magic specifies that it does not work on instantaneous spells.

2: The last line of Sculpt Corpse states, "Any spell or effect that targets the corpse (such as speak with dead or raise dead) treats it as if it still had its original appearance."

Restore Corpse specifies, "The corpse looks as it did when the creature died." Thus, I would rule that restore corpse returns the corpse to its original appearance.

3: I don't believe you would need to take this step, but it would definitely work if the GM disagrees with the interpretation of Restore Corpse above.

"Excellent... go forth my necromancing Compatriot, and continue your noble work in Perfecting these lands through Undeath, and expunging its weakness of flesh.... "

[Ryze Kuja]

1) Correct, Dispel Magic would not remove it.

2) This is debatable, but I agree with MargarineMeadow that Restore Corpse would indeed work.

3) Also debatable, but I would say yes. Decomposing and then Restoring the Corpse would work as well.
