Transparent Object

An object no bigger than 5 feet cube, you spell into becoming transparent (invisible).  It stays invisible for 8 hours.  It can be dispelled.  It can be touched and interacted with.  It cannot be used to damage or attack another creature without breaking the spell. 

At Higher Levels. 3rd level, you can affect an item 10 feet cube, and invisible for 24 hours.  At 4th level, you can affect an object (or building), up to 30 x 30 x 30 ft, also all objects spelled at this level stay transparent for 1 moon cycle if cast by the light of the full moon.  At 5th level a medium object stays transparent until it is dispelled or until you create another medium transparent object.   At 6th level an object up to 50 x 50 x 50 stays transparent as long as you agree to give up a 6th level spell slot daily for the spell thread.    Note: DM, get creative with upgrades that seem proper.
