Ricochet

With careful judgments of distances, materials, wind, and applied force you let loose a shot that bounces off of one or more surfaces to strike opponents crouching behind walls or otherwise hidden from sight by cover.

On the next ranged weapon attack you make before the start of your turn, you can completely ignore a target’s cover . 

Only targets that have total cover from being entirely enclosed by an object or effect (such as inside of a chamber with no openings to shoot through or a sphere from wall of force) have cover against this attack, and you do not have disadvantage from attacking a target you cannot see.
