As an action, a swirling cloud of smoke shot through with white-hot embers appears in a sphere centered on a point within 35 meters. The cloud spreads around corners and is heavily obscured. It lasts for the duration or until a wind of moderate or greater speed (at least 16 kilometers per hour) disperses it.
A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Fortitude saving throw.
On a failed save, a creature takes 2d6 fire damage and is burning 1.
On a successful save, a creature takes half as much damage and doesn’t start burning.
The cloud moves 3 meters away from you in a direction that you choose at the start of each of your turns.
You can increase the damage by 1d6 for each additional mana or psi expended.
