Evil Eye of Weakness

You turn a vile gaze toward a creature of your choice within range that you can see. The creature must make a Constitution saving throw or feel weakened and move slower. On a failure, roll 1d6 at the start of your turn. The enemy creature receives a penalty to their attack rolls and ability checks based on Strength or Dexterity equal to the number rolled that turn. The creature may repeat this saving throw at the end of it's turn. The spell also ends if the target is ever outside the spell’s range or if it has total cover from you.
