Are you referring to the Resurrection Wisp item ? That ' s suppose to revive a fellow friendly human . <| sep |> Suppose BoltonFrey are more loyal and Edmure doesn ' t screw up and repel Tywin . Robb ' s plan had been to lure Tywin back into the Westerlands and crush the Lannister army , possibly taking Tywin prisoner . Sure thing ? No . But given that Robb ' s builtup to be this outstanding military commander , it ' s possible . I think the TyrellLannister alliance was already negotiated at that point so Stannis still would ' ve been broken at Blackwater , but it would have been much costlier since it would ' ve been a Tyrell relief force instead of a TyrellLannister relief force . At that point , the North is led by Robb , fresh off of glorious victories in the Westerlands and Riverlands , and the Lannister camp is led by strategic genius the Mountain .
