Ill Omen

Source ill omen

For the target's unlucky d20 rolls, it must roll three times and take the lowest result. Spending a move action to utter a prayer or good luck charm allows the target to roll twice instead of three times.

Augmented (4th): If you expend two uses of mythic power, you afflict the target with especially foul luck. Any natural 20 it rolls counts as a natural 1 instead.
