Summoner's were always one of the best choises to kill wyrms but now Ouryu/Jorm/Tiamat are competely easy.
His ranged atk was doing from 250-258 constantly, I never saw a resist which ment you could get 750 dmg in per SMN in the air (if they fix the admn BP thing). It basically cut the fight time in half. It is greatly effected by Darksday because it started doing 300 dmg when darksday hit.
Finally.. Thank you SE for something nice>_>
