As an action, a tidal wave surges forth from you or retreats to you. Each creature on the ground other than you in a sphere centered on you must make a Reflex saving throw. Choose to have the wave surge or retreat.
On a failed save, a creature takes 1d8 bludgeoning damage and if it is Medium or smaller it is knocked prone and pushed up to 3 meters away from you or pulled up to 3 meters closer to you (pushed if it surged, pulled if it retreated).
On a successful save, a creature takes half as much damage and isn’t knocked prone or pushed or pulled.
Additionally, any burning creature or object in the area stops burning and unprotected flames in the area are extinguished.
You can increase the damage by 2d8 and affect a creature of a larger size for each additional mana or psi expended.
You can expend 2 additional mana or psi so the waves surge continuously. The duration changes to 1 minute/mana, concentration and the waves surge toward and away 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 Reflex saving throw.
You can change the direction of the waves as an action.
The damage is reduced to 1d4 and additional augments to the damage increase the damage by 1d4 for each additional mana or psi expended, instead of the normal increase.
