Evokes a whirling cylinder within which one or more persons can hide from certain Mythos creatures. A small bronze disk etched with a specific arcane symbol is required. The caster lays the disk on the floor, stands atop it, intones the words of the spell and expends the spell’s cost. With success, it generates a 5-foot-diameter wheel of spinning blue mist around the caster. Everything within the wheeling cylinder of mist is totally obscured. The wheel takes 1D3 minutes to form completely, lasts for 1D20+10 minutes, and then dissolves.

The mist hides people from creatures summoned by Nyarlathotep or in the name of Nyarlathotep. Such a creature acts as if the mist and those obscured by it are not present. The creature will not move through the wheel’s position, even by accident. If the wheel blocks a path, the creature stops where it is or goes backward without knowing why. The wheel only affects summoned minions, never Nyarlathotep.

As many people as can crowd into the mist can be obscured by the wheel; however, if one’s feet, head, etc., stick out then the illusion is ruined for all (such aspects are at the Keeper’s discretion). To hide a group of normal height investigators, 7 magic points are needed.

Creatures present before the wheel of mist is cast or called up by power other than that of Nyarlathotep can see the wheel and move into it. A person may step out from the wheel but this will ruin the illusion if the stepper is spotted, as does passing anything through the mist, such as a bullet or a sword. Once the creature’s attention is caught and it realizes that an illusion is in progress, the protection of the spell is lost.
