Alright time for the big guns!
Casting Time: 1 action
Components: V, S
Duration: Concentration, up to 1 minute
You become a being of pure thought. Your body enters the ethereal plane but you remain conscious of and can interact on both the plane you were just on and the ethereal plane. You are immune to all non-psychic damage or mental effects. You are instantly aware of and can track all thinking creatures within 10 miles of your current location so you cannot be sneak attacked or surprised. While the spell is active you can cast hold monster, dominate person, confusion, counterspell, and dispel magic at will.
When the spell ends, you immediately pass out and awake 1 hour later unless revived via restoration or other like means.
