As an action, searing flames bursts out from you. Each creature other than you in a sphere centered on you must make a Fortitude saving throw.
On a failed save, a creature takes 3d6 fire damage and is burning 1.
On a successful save, a creature takes half as much damage and doesn’t start burning.
You can increase the damage by 3d6 and the burning level by 1 for each additional mana or psi expended.
Blazing Inferno. You can expend 1 additional mana or psi so the flames around you are continuous. The duration changes to 1 minute/mana, concentration and the flames spread out from you in an aura shaped as a sphere. Until the spell ends, the aura moves with you, centered on you.
Whenever a creature enters the area for the first time on a turn or starts its turn there, it must make the Fortitude saving throw. The damage is reduced to 2d6, additional augments to the damage increase the damage by 1d6, and don’t increase the burning level for each additional mana or psi expended, instead of the normal increase.
