Smoky form

Smoky form was a common spell used by wu jen in Kara-Tur. The spell was very rare outside Kara-Tur.

Effects
When cast, this spell transformed a wu jen into a mass of thick smoke. The wu jen's clothing and equipment was also transformed. The spell also affected any creature in physical contact with the wu jen at casting. The resulting cloud of smoke had the same shape and appearance of the individual. For the duration of the spell, an individual is immune to physical attacks. Further spells cannot be cast while the wu jen is in smoke form.

While the actual mass of the individual is not altered, their weight becomes the same as smoke. So an individual in smoky form cannot squeeze through cracks in a wall, but could drift down from cliff. While in smoky form, the individual is vulnerable to wind, which caused them to move in directions they could not control. Spells such as gust of wind or wind breath inflicted damage to an individual in smoky form, and the divine wind spell killed the individual.

Components
In addition to verbal and somatic components, the spell required a material component, some burning incense.
