Tidal Surge

You summon a crashing wave of elemental water that surges forward in a 30-foot-long, 10-foot-wide line originating from a point you can see within range. The wave slams into creatures and objects, knocking back foes and cleansing allies.

Effects:

• Enemies: Each creature in the area must make a Strength saving throw. On a failed save, a creature takes 4d8 bludgeoning damage, is pushed 15 feet away from the wave’s origin, and is knocked prone. On a successful save, the creature takes half damage and is not pushed or knocked prone.
• Allies: Allies in the area are washed in restorative waters. They are cleansed of one condition (your choice of charmed, frightened, or poisoned) and gain temporary hit points equal to your spellcasting modifier.

At Higher Levels. When cast using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd, and the push distance increases by 5 feet.
