Stymied Hopes

You attempt to interfere with a creature in the process of casting a spell, forcing it to expend additional magical energy to continue the casting. At the same time, you steal this energy for your own, and use it to help yourself divine the future. If the creature is casting a spell of 2nd level or lower, it must expend an additional spell slot of 1st level or higher, otherwise its spell fails and has no effect. Then, if its spell fails, roll a d20 and record the result. Once before the end of your next short or long rest, when you roll a d20 you can choose to replace the roll with the recorded one. You can do so after seeing the roll, but before you know the result. If you have already cast a spell that allows you to roll any number of d20s and record the results, you lose the results of any previously recorded rolls.   At Higher Levels When you cast this spell using a spell slot of 3rd level or higher, the level of spell affected and the level of the spell slot that must be expended both increases by 1 for each slot level above 2nd.
