Reverie Knights Tactics

During the story plot Fren will make a poor decision, you can choose to either Forgive him or Banish him. These are mutually exclusive choices but if you save right before making the decision ( a good habit is to save after each node battle before progressing to the next and activating the story arcs) you can reload and choose the other option to unlock both in a single playthrough.

Note: If you choose to banish Fren he leaves the party but only for a few battles before returning. The game forces you to accept him back.
