One creature you can see within range begins twitching its fingers uncontrollably. While the spell is in effect, an affected creature must make a successful Wisdom saving throw to cast a spell with a somatic component; if the saving throw fails, the intended spell fails and the spell slot is expended. An affected creature also must make a Wisdom saving throw before making a Dexterity check that requires fine control of the hands, such as using thieves’ tools; if the saving throw fails, the Dexterity check fails automatically. A successful Wisdom saving throw ends the spell effect.
