Summon Fog

The kami can be petitioned to coalesce in an area as they do on the coast, creating a thick, obscuring fog. Within the area affected by your spell, the visibility is decreased to a meager five feet. Fabrics and other absorbent materials within the spell's area of effect will become damp or even wet if they remain within it long enough. Small sources of open flame, such as candles, might be extinguished as well, at the GM's discretion. The moistness of fog is extremely damaging to rice paper.
