Timbo's Earsight

This spell gives the willing creature you touch heightened senses. For the duration, the target can focus on it's hearing as a bonus action, granting it blindsight out to a range of 20 feet until it is deafened or until the start of it's next turn. While the target benefits from the blindsight granted by this spell, it is blind beyond it's radius.

At Higher Levels. When you cast this spell with a spell slot of 3rd level or higher, the radius of the blindsight is extended by 5ft for each spell slot level above 2nd.
