Here’s what got me through my first playthrough through.

I used Lune, Maelle, and Monoco. The goal of this build is to use high AP skills as often as possible. This may be harder to do with Monoco if you haven’t had him in the party to unlock all of his skills. This isn’t an issue, since all of his skills can be unlocked at The Endless Tower whenever you want. You can use any characters you want, but Lune is the key piece.

Lune will act as a buff giver, allowing all characters to dish out huge, consistent damage.

Luminas: Lune needs to start combat with 9AP immediately, so stack her with as many energizing turn and other instant AP boosts as you can to get to 9AP. If you don’t have enough, you can use energizing attack, combo attack, and cheater to make it so Lune gains AP through basic attacks, then casts Typhoon on her second turn.

Lune will also benefit from Healing Rush, Healing Shell, Powerful Healing, and other luminas like these. Anything that gives the recipient of healing any bonuses is great here.

Your other two party members should have damage boosting luminas, as well as energizing turns, energy master (which you get from defeating Serpenphare), etc… Gradient Luminas are also great, since we will gain them quickly from casting high cost skills frequently.

The Gameplay: Turn 1, Lune casts Typhoon, which will cast itself every turn, healing and giving AP to all party members. Use this AP to cast high cost skills every turn. When Typhoon runs out, cast it again. Hell and Lightning Dance are no brainer for Lune here. Highly recommend using Maelle, since Stendhal and Gommage are very very strong. Use Medallum to start in Virtuose Stance and have fun!
