The Spell of Humility is a spell cast by the Roman Magus in C.E. 10 causing gargoyles' clothes and other items on their person to enter stone sleep with them, thus preventing nudity upon awakening at dusk. The spell was clearly quite powerful since it managed to affect every gargoyle in the world (including those the Roman Magus was presumably unaware of such as the Mayan Clan) and continues to affect them throughout all time beyond C.E. 10. The Roman Magus used a combination of various magical artifacts to achieve this amazing feat.
