Hunter's Surprise

This is a Advanced Rogue Talent — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

Once per day, a rogue with this talent can designate a single enemy she is adjacent to as her prey. Until the end of her next turn, she can add her sneak attack damage to all attacks made against her prey, even if she is not flanking it or it is not flat-footed.
