Scratches head, maybe I'm just confused by the wording :
Misfortune (Ex): At 1st level, as an immediate action, you can force a creature within 30 feet to reroll any one d20 roll that it has just made before the results of the roll are revealed. The creature must take the result of the reroll, even if it’s worse than the original roll.
Let's say DM rolls X for a monster. You say, "misfortune time". He rolls Y. Regardless of what X was (since you don't know it), it picks Y, ignoring X entirely. Thus, the actual value of X is irrelevant to all actors, you, Y, and the DM and even the monster. Nobody has a choice in the matter to pick X over Y, it's always Y. So how does this grant "misfortune" at all? Y could be greater than X for all you know. Each die roll does not influence the other in any way, since you can't compare them at the time of choosing which gets used.
//still scratching my head on this one.
