Eberons Wrath

Description: With a cry of rage and despair, the sorcerer unloads his pent-up emotions in an explosive discharge of energy. Each creature within a 20-foot radius of a point of your choice within range must make a Dexterity saving throw. On a failed saving throw, a creature takes 5W8 lightning damage and is knocked back for 1 round. On a successful saving throw, the creature suffers only half damage and is not pushed back.
In addition, any creature hit by this spell gains disadvantage on attack and ability rolls until the end of its next turn as it is overwhelmed by the caster's reverberating emotions.
Higher Levels: If you cast this spell with a 4th or higher level spell slot, the damage increases by 1W8 for each level above 3rd.
