Not There

3rd-level illusion

Casting Time: 1 action

Target: Self

Duration: Concentration, up to 1 hour

Components: V, S, M (a small bottle with a dying man’s last breath inside)

Classes: sorcerer, warlock, wizard

You become invisible, as per the spell invisibility, but you also gain the ability to step onto the ethereal plane for a brief period of time. Stepping onto the ethereal plane takes a bonus action, and you remain there for 1 round. At the end of that round the spell’s duration expires, and you return to the material plane. If you return to the material plane in a place you cannot occupy (such as a solid object or within another creature), you take 1d10 force damage, and are shunted into the nearest space you can occupy.
