Twist of Fate

You cause a violent shift in fate, when a creature that you can see within 60-feet of you rolls an Ability Check, Attack Roll or Saving Throw either with Advantage or Disadvantage, you can use your reaction to potentially alter the outcome. Before any roll is made, but after Advantage or Disadvantage is called, you can reverse the effects of the roll. For example, if a creature rolled with Advantage, it now rolls with Disadvantage and vice versa.
