Toil and Trouble

You intensify the worries and physical exertions weighing a creature down. Choose up to three creatures of your choice that you can see within range. The creatures must make a Wisdom saving throw. Whenever a target that fails this saving throw makes a Strength or Dexterity attack roll or saving throw before the spell ends, the target must roll a d6 and subtract the number rolled from the attack roll or saving throw. The target can make a Wisdom saving throw at the end of each of its turns. On a succes, the spell ends. For each three turns the target is under thsi spell, they gain one level of exhaustion.
