Chronolusion

You touch an object, no larger than two feet in any dimension, and choose a specific point in the past that it existed. You cause that item to appear and feel as it did at that point. For example, if you used this spell on a book that was burned, and you chose the point in time that it was newly minted, you cause it to look and feel like it was brand new.

If an object affected by this spell becomes wet from the slightest amount of water, is harmed, or is physically modified in any way, the effect is dispelled and reverts back to its original form.
