Cloud

Elements: air or water Type: form infusion Level: 7 Burn: 4 Prerequisites: extended range Associated Blasts: blizzard, sandstorm, steam, thunderstorm Saving Throw: none You release your power in a diffuse cloud. You can center this 20-foot-radius spread anywhere within 50 feet of you. Any time a creature enters the cloud, it takes half the normal amount of damage from your blast, as do creatures that end their turns in the cloud. It lasts for a number of rounds equal to your Constitution modifier or until you use the cloud infusion again.
