Azuth's Manifested Mind

As a bonus action, you can cause your mind to manifest as a Tiny spectral object, hovering in an unoccupied space of your choice within 60 feet of you. The spectral mind is intangible and doesn’t occupy its space, and it sheds dim light in a 10-foot radius. It looks like a ghostly tome, a cascade of text, or a scholar from the past (your choice).

While manifested, the spectral mind can hear and see, and it has darkvision with a range of 60 feet. The mind can telepathically share with you what it sees and hears (no action required).

Whenever you cast a wizard spell on your turn, you can cast it as if you were in the spectral mind’s space, instead of your own, using its senses. 

As a bonus action, you can cause the spectral mind to hover up to 30 feet to an unoccupied space that you or it can see. It can pass through creatures but not objects.

The spectral mind stops manifesting if it is ever more than 300 feet away from you, if someone casts dispel magic on it, if you die, or if you dismiss the spectral mind as a bonus action.
