Augmented (2nd): If you expend two uses of mythic power, the target ammunition or weapon returns to the creature that shot or threw it just before that creature's next turn (similar to a returning weapon). The spell isn't discharged until the target is used to attempt a second attack against the named creature. Ammunition that hits is destroyed and doesn't return.
