Spell of Humility
From Multiversal Omnipedia
The Spell of Humility was cast by the original Magus in AD 10. It caused all gargoyles on the planet to have their clothes, and any possessions they considered part of them, to turn to stone when they did. The Spell was created as a response to the public indecency problem created by gargoyles when they tore out of their clothes upon awakening from stone.
