As a reaction, which you use when another creature within 10 meters that can hear you makes an attack roll, an ability check, or a saving throw, you can use your wit to distract, confuse, and otherwise sap the confidence and competence of the creature. The creature makes the roll with disadvantage. The creature is immune if it can’t hear you or if it’s immune to being charmed. You can do so after the roll but before any effects of the roll occur.
If the roll already has advantage or disadvantage, you cannot apply another instance of advantage or disadvantage and you must use this before the roll to cancel out any advantage or disadvantage.
You can use cutting words against one additional creature for each additional breath expended. The creatures must be within 5 meters of each other when you target them.
