Astral Body

You spend an action to exit your physical body and essentially become a ghost. For as long as the spell is active your original body is prone but you can move anywhere as a ghost (including through walls and closed doors) within a 30ft radius of your body. As a ghost you are invisible to others, however moving through them causes a subtle chill to go down their spine. You can see and hear things but senses like smell, touch and taste are lost. The spell is cancelled if you take any amount of damage, if another concentration spell is activated, or if the duration wears off.
