Throw Shade

Your words cut deeply into the confidence of a target you can see within range, and those words continue to be heard by it until the spell ends. If the target can hear and understand you, it must succeed on a wisdom saving throw  or have disadvantage on ability checks and attack rolls for 1 minute. For the affected target the world seems to darken and it doubts its own abilities. A  creature that is immune to being charmed is unaffected. The target may use an action to use another wisdom save. On a success the spell ends and the target regains focus and self confidence.

At higher levels: When you cast this spell using a spell slot of second level or higher you can target 1 additional creature for each slot level above 1st.
