Crippling Visions

The victim of this spell, once used, will be put in a vision of the end of the world and everyone and everything they love burning to the ground. they temporarily forget everything that was happening and are lost in despair, rendering them functionally immobile until contact is broken. they must make a WIS save. upon succeeding, they start to remember who they are and start forcing their way out of the vision, and upon a failure they begin to go slowly insane, and contact is no longer necessary, instead lasting an hour. on a nat 20 they break free instantly and a nat 1 drives them irreversibly insane with grief
