Smoke Screen

This spell creates a large sphere of thick, black smoke. The smoke always floats 2 feet above the ground, and creatures below the cloud can breathe normally. Otherwise, creatures in the area of effect take 1d4+1 points of damage per round from smoke inhalation; half damage is taken if a saving throw vs. spell is successful.

It is not possible to see into or through the area affected by a smoke screen, and visibility within this area is reduced to 2 feet. The reduced visibility makes combat difficult; attack rolls are made at a -3 penalty. A gust of wind spell extends the cloud along its full length, preventing the damage effect and reducing the duration to no more than 1d4 rounds.

The material component of this spell is a pinch of soot.
