An early attempt to use the magic of Air to gain advantage against the unwary, the Soshi family devised this spell to delay those who had stumbled upon their Clan’s machinations, or to cover their tracks. Once this spell is cast, the next thing the victim sees that seems unusual or out of the ordinary instead appears completely normal to them. This does not change the victim’s reaction, it simply clouds their perceptions such that they believe they are seeing something they expect to see, or at least something not unusual at all. A guard under the influence of this spell, for example, might walk through his regular patrol and see an undisturbed room rather than the ransacked mess a thief had left behind.
This spell only affects vision, so the victim is allowed an Investigation roll against a TN of the caster’s Air x 5 if there are subtle clues betraying the illusion (such as stepping on a bit of spilled sake). Any major clues (such as screaming coming from the changed scene or tripping over an object covered by the illusion) ends the effect immediately.
