Shallal Magd

Shallal Magd (隠者の水膜 （シャラール・マグド）, Sharāru.Magudo, Water Membrane of the Hermit) is a type of Water Magic. Yamraiha gives Rukh 3 commands: “gather the water”, “change the water to steam”, and “manipulate the refraction of light”.

By manipulating the refraction of light in water vapor, it erases a person from other people's line of sight or, in other words, making the caster invisible to others.

Trivia
