Vaarsuvius' Enhanced Scrying

You can see and hear a particular creature you choose that is on the same plane of existence as you. 

The spell creates an invisible sensor within 10 feet of the target.  You can see and hear through the sensor as if you were there.  The sensor moves with the target, remaining within 10 feet of it for the duration.  A creature that can see invisible objects sees the sensor as a luminous orb about the size of your fist. 

Instead of targeting a creature, you can choose a location you have seen before as the target of this spell.  When you do, the sensor appears at that location and doesn't move. 

This spell cannot be blocked by any spell of 7th level or lower. 

At Higher Levels.  When you cast this spell using a spell slot of 8th level or higher, it can't be blocked by any spell of a level equal to or lower than that of the spell slot used.
