Delocalize Mind

You create an autonomous copy of a small piece of your mind and anchor it into the physical world. The mind takes the form of an invisible, shapeless mass and has 1 hit point and AC of 10. It occupies a 5 ft space and cannot move. Moving the mind from the spot where it was cast ends the spell.

When you cast this spell, choose another spell of 4th level or lower that requires concentration. For the duration, when you cast the chosen spell within 30 ft of the mind, it will assume concentration of the spell in your place. It will concentrate for the full duration of the chosen spell, so long as you remain within 30 ft of it. If you cast anything besides the chosen spell, if the mind is concentrating and the chosen spell is cast again, or if the chosen spell is cast in the effective area by someone other than you, the mind will not assume concentration. Casting the chosen spell in the effective area of the mind will still consume a spell slot.

As an action, you can reassume concentration of the chosen spell, or shift it back to the mind. If you leave the effective area of the mind while it is concentrating, the chosen spell will end. If the chosen spell ends, the mind can still concentrate on subsequent castings for the duration of its existence.

This spell ends after 8 hours, or if the mind is destroyed or dispelled.
