in my case, you need to be level round 40 ish. oh yeah, it is possible to win the battle without using true awaken pronant. when phase 2 started, you need the oldest sister's field to counter wind attack. and also, asap wipe all 4 brothers 1st. the build eq? u need the armor from this second town where you need the blood as the ingredient. and also dont forgot to equip wind/earth resist accessory(?). swan slash is bullsheet. but you need golden slash skill tho for big damage on isorath(?). unless the field is in brawl state then you can abuse swan slash. always buff irito and julios. and irito need to equip unremoval buff tome, i forget the actual name for the tome.
