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 targets must make a Wisdom saving throw.

On a failed save, whenever a target makes a Strength or Dexterity saving throw before the spell ends, it must roll a d6 and subtract the number rolled from the saving throw or attack roll.

The target can repeat the Wisdom saving throw at the end of each of its turns, ending the effect on a success.

For each three turns a target remains under this spell’s effect, it gains one level of exhaustion.
