Arcane Vision

For the duration of the spell, you can see through yours eyes a magical aura around people or objects in an area of 150ft from you. A blind caster can't cast this spell

A person can have an aura around him that identifies the type of magic (arcane, druidic, divine, or pact magic) and can see the level of the available spell slot more high (if the highest has already been consumed then it will be shown
the next one).

An object can have an aura around it that identifies the school, level and (if known) the spell applied to it. Vision is obscured by an antimagic field or magical barriers such as a wall of force. The spell can penetrate many barriers, but it comes blocked by 3ft of stone, 1 inch of metal or 9ft of wood or earth.
