Age/Rejuvinate Object

A nonmagical object you touch for the entirety of the casting time has its age increase or decrease by 2d8 days. If an object's age is increased past the point of it being able to function properly, the DM determines how its composition and operation are altered.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the object's age increases or decreases by 2d8 additional days for every level above 2nd.
