Become god (V3)

You muster all of your arcane power and channel into yourself or a willing creature. The creature to self makes wisdom save and beat a DC15 save or go mad. If the creature succeeds it suddenly glows so brightly everything must look away or take 2D10 radiant damage. The affected creature or self becomes a god and a new plane of existence is created. The creature has complete control over the plane and can banish or summon a creature to and from the plane.  Any creature that sees this transformation must make a wisdom save or become obsessed with the new god. If the caster does not choose him/herself for the spell they immediately disintegrate and can only be resurrected by  Divine Intervention. The divine intervention can be from the newly created god. The stats of the new god are determined by the DM, but the god is now immortal and if killed will return to their plane, and can't do anything for 1D4+3 days. Anything in the plane is determined by the new god. If a creature enters or exits the plane the new god instantly knows. If the new god is the spell castor he/she has no recollection of past events. The new god has infinite powers in their plane unless stated otherwise by the DM.
