Alain Robert’s Bag of Chalk

Origin
Alain Robert is a rock climber and urban climber known for his various climbs up famous skyscrapers such as the Eiffel Tower, Petronas Twins Towers, Sydney Opera House and Burj Khalifa, all of varying legality. He has been arrested, jailed and fined many times for illegal climbs after he has completed climbs, twice at the Petronas Towers. Known as the French Spider-Man, most of his climbs include little to no safety equipment, with only his sneakers and a bag of chalk to enhance his grip; he has had seven falls throughout his career.

Effects
When rubbed on the hands, they enhance grip on anything they touch. They work best on concrete and steel, although they work just as well on wooden and glass structures. The user’s handgrip and adhesion are exponentially increased, allowing them to scale walls with ease. However, the user experiences strong surges for climbing the nearest building, no matter the legality of the act.
