I think the writing on how the spell works needs a small revision. As written when you chose misfortune, the target doesn't save immediately but on their next appropriate roll rolls twice. After they roll twice then they make a will save, which on a failure must use the lower roll, but doesn't state which to use on a success. This means whoever is under the effect would have to state which of the dice is the "original" roll to be taken on a success. I think it would be a lot cleaner if when choosing misfortune the target saved immediately to negate the effect even if this would be a very minor functional change and perhaps take slightly more words.
