Almighty Assault

As part of the action used to cast this spell, you must make a melee weapon attack against one creature or location within the spell's range. Depending on the damage type the weapon deals, the spell has a different area of effect:

• Slashing. A crescent of energy races from the attack, and each creature in a 20-foot cone in the direction of the target must make a Dexterity saving throw. 
• Piercing. A pure beam of energy streams from the attack, and each creature in a 60-foot long, 5-foot wide line must make a Dexterity saving throw. 
• Bludgeoning. Explosive energy emanates from the attack, and each creature other than you within 10 feet of the target must make a Dexterity saving throw. 

Creatures failing their saving throw take 2d10 radiant damage, are pushed 10 feet back, and fall prone. A creature that was hit by your attack has disadvantage on the saving throw.
