Otiluke's Steaming Sphere

This spell creates a small crystalline sphere filled with hot steam in the caster's hand. The mist within the sphere remains active for three rounds. The sphere can be hurled up to 60 yards from the caster. When the sphere hits a solid surface, it instantly shatters, filling a 30-foot radius area with thick steam that inflicts 4d4 points of heat damage per round of exposure, with no saving throw.

The steam totally obscures vision, reducing visibility to only 3 feet. Creatures within the affected area are disoriented, making it difficult for them to find their way out of the steam cloud. To escape the steam cloud, a creature must make a successful saving throw vs. spell, with one attempt allowed per round. A creature that successfully saves emerges from the steam bath in a random direction; Imagine a clock face and roll 1d12 to find the direction in which the creature escapes. If the saving throw is failed, the creature stumbles around in the steam bath for that round. Once activated, the steam lasts for one round for every two levels of the caster. It can be dispersed at once by a gust of wind spell.

The material components are a few drops of pure water, a pinch of dust, and a bit of sulphur.

Notes: Uncommon or rare spell (WoG).
