Need help on Yunalesca, I have used all of my lvl ups, I have enough farplane winds but no Holy magic and not enough holy potions or what they are called to make a armor protective. Any tips on beating Yunalesca anyway? I have already used all my lvl ups on the sphere grid and have good HP on everyone but miss out on some spells, is there anyway to beat her without running back and lvl?

Appreciate some help /ickash
