As an action, lightning expands from you, zapping all nearby creatures. Each creature other than you in a sphere centered on you must make a Reflex saving throw.
On a failed save, a creature takes 2d10 lightning damage and it can’t take reactions until the start of its next turn.
On a successful save, a creature takes half as much damage.
You can increase the damage by 2d10 for each additional mana or psi expended.
Storm Pulse. You can expend 1 additional mana or psi so the lightning around you is continuous. The duration changes to 1 minute/mana, concentration and the lightning erupts around 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 Reflex saving throw. The damage is reduced to 2d6 and additional augments to the damage increase the damage by 1d6 for each additional mana or psi expended, instead of the normal increase.
