"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. Once a creature has suffered from your misfortune, it cannot be the target of this revelation again for 1 day."
But there's nothing that seems to give the oracle more uses per day, even tho the last line clearly implies it can happen.
The other ability sez "You can use this ability once per day at 5th level, and one additional time per day for every six oracle levels beyond 5th."
I've always assumed it's like witch hexes.
Unlimited uses per day, but only once per creature.
I agree that it's like the witches Hex, you're only limited by the number people who roll D20s within 30ft of you.
Yeah we had our oracle in a pfs session last night using it on party members when they rolled low. I had never seen that before but it was pretty fun.
Yup, it was written a certain way and is used that way.
Not something I'd ever allow in my home games. :p
