invisible air (fate)
In the Fate series, Invisible Air is a sheath of magical wind that makes Saber's sword Excalibur turn invisible.
Invisible Air is initially presented as Saber's main Noble Phantasm. As the sword is invisible, use this tag when there is evidence the sword is being held (such as it having blood on it) or that its ability to control wind is being utilized. If another sword is shown as semi-transparent, tag it with both the name of the sword and invisible air.
