Duplicating Object Curse

This spell has the Hex tag. Choose an object within range. Whenever that object is touched or affected by a spell, a second identical object appears next to it. If anyone touches any duplicates created in this way or casts a spell on it, the duplicate creates another duplicate. The objects can keep doing this to a maximum of 100 duplicates. All of the duplicates disappear at the end of the duration. This can be stopped by Dispel Magic, Remove Curse, Undo Transmutation, or the Wish spell.

At Higher Levels. When casting this spell using a spell slot of 7th level or higher, the duration increases by 24 hours per spell level and the maximum number of duplicates doubles. When cast at 9th level, you can have the duration be as long as 1 year and have unlimited duplicates. If cast on on object at 9th level for 13 years, it is permanently under the effect of the Duplicating Object Curse, and spells such as Dispel Magic only stop the effects for 24 hours rather than ending the spell, and nothing short of a Wish spell or divine intervention can remove it.
