since the cost update just get as many 7 star as you can, doing it at lv 150 with 5 7 stars was not fun

Use laberd lead, charla (her only job will be as a healer / status ailment remover since shusui is resisant to everything), gildorf (damage) and iris (elemental mitigtion & adding water types to attacks). I would assume you have alot of haile friends, use of of them its your best bet, if not even some damage like OE eze, as long as they have some hp LS or else you wont survive.
