Transmutate

This spell allows you to manipulate the makeup of an item on a molecular scale for a brief period.
Touching a small nonmagical item or smaller, you can cause one of the following effects for 10 min. You can cast the spell multiple times and have up to 3 effects going at a time.

• Cause the item to revert to a previous state it once held within the last hour 
• Cause the outermost layer of the item into a different substance you are familiar with
• Cause the item to change color
• Cause the item to form a tiny structure or deformity (Cause a carving to form in a log, cause a watch's hands to appear phallic, etc)

This spell can be upcast. Each increasing spell slot level adds 10min to the duration of the effect.
