You jump and fly forward 10 feet from the power of your leap, anybody below you within a 5-foot square will get hit by a dark magic blast created by a downwards sword slice. Unlike abyssal scream, this hit is dodgeable and has a hit DC roll. Any creature hit with the attack will take a WIS saving throw, if they succeed the attack damage will be cut in half and the spell effects will be nullified, if they fail they will take the full damage and the next attack the caster takes on the hit creature will have advantage
