By wrapping yourself in strands of chaotic energy, you gain advantage on the next attack roll or ability check that you make. Fate is a cruel mistress, however, and her scales must always be balanced. The second attack roll or ability check (whichever occurs first) that you make after casting shifting the odds is made with disadvantage.
