I'm about to go into the Stilshrine after the Paramina Rift, and my entire group is Level 27-28. Most of my characters have between 1200-1300 HP, and I think Fran and Basch have over 1400. I only have the basic black magic skills on everyone, but they all have white magic skills up to Cura, Raise, Esuna, etc. I struggled a lot during the last boss battle, but I've already done a lot of grinding. Is this good? :S How much grinding should I be doing if I simply want to complete the game's main story?
