Astral Discourse

You and up to eight willing creatures anywhere within the same plane of existence project your astral forms into a created Astral Chamber within the Astral Plane for 10 minutes (the spell fails and the casting is wasted if you are already on that plane). The material body you leave behind while within the Astral Chamber is unconscious and in a state of suspended animation; it doesn't need food or air and doesn't age.

Those chosen to participate, if not directly beside the caster, understand who is asking them to enter the Astral Chamber. They also understand that it cannot be forced and if they reject the call to their astral form then the spell will fail on them alone; this does not effect any other participant or the spell.

The Astral Chamber is purely for the purpose of discourse; it is protected from the dangers of the Astral Sea and any divination magics that may attempt to penetrate within. While inside the chamber, any attacks fail and no harm can befall the participants. Melee or ranged attacks phase through the body of individuals as if their form is not fully there and magic may have bizarre or beautiful backfires e.g. fireball may detonate into a flurry of butterflies.

The spherical chamber has a radius of 60ft and their is no floor. The place is furnished and decorated as you choose, but the outer shell will always show the vast expanse of the Astral Sea. Astral forms within the chamber can move as if they are on the Astral Plane itself; a participant can move by simply thinking about moving. The smarter a creature is, the easier it can control its movement by act of will.

When the spell ends, any astral forms inside the Astral Chamber are expelled back into their bodies.
