Butterfingers!

Choose a creature that you can see within range. The target's hands (or equivalent appendages) suddenly get clammy and sweaty, or coated in an otherwise slippery substance, and must succeed on a Strength or Dexterity saving throw, their choice, equal to your spellcasting save DC. If they fail, they drop whatever they are holding while exclaiming "Butterfingers!" if the creature is capable of speech. If they succeed, nothing happens. To pick up whatever they dropped, they must use their action. If they have another weapon or item they wish to draw, however, this will not use their action and they can draw it as normal.

At Higher Levels. Add +2 to the saving throw DC for each slot level above 1st.
