Smoldering Ray

You hurl a ray of shimmering heat at a creature within range. Choose one target you can see. Make a ranged spell attack. On a hit, the target takes 2d6 fire damage, and their body begins to smoke. Until the start of your next turn, the next weapon attack roll they make is made with disadvantage, as heat radiates off their skin and sears their focus.

At Higher Level. When you cast this spell using a spell slot of 2nd level or higher, you can create one additional ray for each slot level above 1st. You can direct the rays at the same target or at different ones.
