Converging Fates

As you are struck by an enemy, you reach into the future and twist together the strands of fate to make your misfortune theirs, as well. For the duration of this spell, whenever the target of your spell is attacked, you may give that attack advantage or if the target makes a saving throw, you may give disadvantage to the saving throw. The spell ends automatically after you give advantage/disadvantage to a roll in this way. The spell also ends if the target leaves the range of the spell during the duration.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you may affect a number of rolls equal to the spell slot used before the spell automatically ends.
