Pure Incendiary Cloud (3.5e Spell)

The incendiary cloud'' spell didn't always suck. Lost to history, a powerful incendiary cloud was created worthy of its high level.''

A pure incendiary cloud spell creates a cloud of roiling smoke shot through with white-hot plasma. The smoke obscures all sight as a fog cloud does. In addition, the white-hot embers within the cloud deal 10d6 points of fire damage to everything within the cloud on your turn each round, and blinds them permanently from the glare of the plasma within the cloud. The fire damage ignores fire resistance, and reduces fire immunity to half damage. Creatures weak to sunlight take double damage, and are treated as having been exposed to sunlight. All targets can make Reflex saves each round to take half damage and negate the blindness, through they are still dazzled for 1 round/level. A creature which is killed by this spell is reduced to ash as the intense flames burn them to cinders.

As with a cloudkill spell, the smoke moves away from you at 10 feet per round. Figure out the smoke's new spread each round based on its new point of origin, which is 10 feet farther away from where you were when you cast the spell. By concentrating, you can make the cloud move up to 60 feet each round, or halt its movement to as low as 0 feet (keeping it immobile via concentration). Any portion of the cloud that would extend beyond your maximum range dissipates harmlessly, reducing the remainder's spread thereafter.

As with fog cloud, wind disperses the smoke, and the spell can't be cast underwater.
