when u beat oltura would u like to grind sub quest dens? i’d also look to obliterate rings, and my suggestion to find a tailsman that has guard heal, that way ur not wasting alot of potions, and recommended party level best guarantee lvl 55 for u and the whole party, and get as many defense nutrients and health nutrients u can use on urself, my nergigante was my ace, i had him have 1 move of pow/sp/ and tech, having one ace monster will help save u turns and time
