Cleave

At 6th level, you learn how to cleave living targets apart in one fell swoop. As an action you choose a target within 150 feet of you. Make a ranged  Attack. On a hit, the target takes 4d12s equal to your proficiency bonus + the amount of Cursed Energy spent in slashing damage.

This attack ignores any kind of resistances since it adapts to the target body. You have advantage against creatures that can't see invisible objects when you use this technique, and being within melee range of a creature who can’t see this technique doesn’t impose a disadvantage on the attack roll
