As an action, you create a visual illusion of yourself that lasts for 1 minute, or until you lose your concentration (as if you were concentrating on a spell).

The illusion appears in an unoccupied space of your choice that you can see within 30 feet of you.

The illusion looks exactly like you; it is silent; it is your size, is insubstantial, and doesn’t occupy its space; and it is unaffected by attacks and damage.

For the duration, you can cast spells as though you were in the illusion’s space, but you must use your own senses, similar to Summon Familiar.
