Warx's Wonderball

You create a two balls of light and throw each of them at a creature you can see within range. Make a ranged spell attack against each target. On a hit, the target takes 2d4 psychic damage, and the target grants advantage to attack rolls made against it for 1 minute. At the end of each of its turns the target can make a Wisdom saving throw, no longer granting advantage on a success.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you create one additional ball per level above 1st. You may choose to target the same creature or different ones with each ball.
