Otto's Gong of Isolation

When this spell is cast upon a creature, the mind-numbing sound of an extremely loud gong fills its mind. If the creature makes a saving throw vs. spell at a -2 penalty, the creature is only stunned for one round. If the saving throw is failed, the creature loses all normal sensory input into the mind. The creature cannot see, hear, feel, taste, or smell, effectively making it helpless. If the creature engages in melee, all attacks are made at -6 penalty, but the creature has no idea of what it is attacking or even if the attack succeeds. Telepathic communication with the creature is still possible, and the creature might receive information about the world through such a link. A heal, restoration, or wish spell completely cures the condition.

The spell requires a miniature gold gong and tiny gold striker with a jade stone as its head, together worth 7,000 gp in materials and workmanship, which does not vanish after the spell is cast.

Notes: Uncommon or rare spell (WoG).
