You alter the composition of one object that you touch, changing it as if much time has passed. Choose either three hours or three days. The object instantly changes as if that much time had passed. This can cause paint to dry and eventually chip away, cause concrete to harden and eventually crack, erode stone, make paper begin to rot, etc.

The rate of change is determined by the object's current conditions: paper will rot faster in warm climates, stone will erode faster if placed in the path of moving water, etc.

This spell can't cause damage to a magic item, and it can't affect any spells or magical effects.
