You infuse your next attack with a curse that imposes an awkward clumsiness in its victim. The next time you hit a creature with an attack during this spell’s duration, your attack deals an extra 1d6 force damage, and the target must succeed on a Constitution saving throw or become cursed for the duration of the spell.   Whenever the cursed target makes an attack roll or ability check using Strength or Dexterity, it must roll a d4 and subtract the number rolled from the result. As an action, the target can repeat the Constitution saving throw, ending the spell on a successful save.   A creature immune to being paralyzed automatically succeeds on its saving throw against this spell. A remove curse spell ends this effect.
