Now that I have light Mona, who should i switch out for her.
Maybe Newbie Mona? Lightbeam Mona might be too weak if you haven't upgraded though.
She's currently 50, with my luck copies are impossible. I also tried Light Mona with Newbie Mona, team nearly dies. So I put sub Newbie Mona for Epona. Due Epona having a debuff Dodger, that helps my leader with her team leader skill.
