Armageddon

When casting this spell, the target must make a Constitution saving throw of 15. On a fail, the target is mentally transported into an unknown realm of absolute Armageddon, everything they do in that realm is only done in the material realm but they can only see and hear the Armageddon realm. Upon "returning" to the material realm, the target is frightened by the user of the spell for 1 hour. On a success, the target is unaffected.
