You field three of the six expeditioners at a time. The strongest comps pair a reliable AP battery with a burst dealer and a support who keeps the Gradient flowing — and always keep an answer for a mistimed parry.
Reliable line-ups
⚖️ Balanced core
Gustave for steady damage and Overcharge, Lune for elemental Stains and healing, Maelle for stance burst. Handles almost anything.
💥 Burst & break
Maelle in Virtuose, Sciel for Foretell setups, Verso to accelerate the Gradient — melts staggered bosses.
🌀 Control
Lune (Stains), Sciel (Twilight/Foretell) and Monoco for flexibility — status pressure and safety for long fights.
Building a comp
- Always bring one character who generates AP quickly to fuel the others.
- Match Pictos/Luminas to the comp — free-aim and parry builds want different Luminas.
- Keep at least one reliable heal or revive so a mistimed parry isn't fatal.
- Cover the fight's element between your three picks so nobody is dead weight.
Flexing per fight
- Swap a member at an Expedition Flag to cover the boss's element or bring a healer.
- Against long fights favour sustain and status; against fragile bosses favour burst.
- Keep one reliable AP battery so your burst characters never run dry.
- Re-tune Luminas alongside the swap so the new trio's passives line up.
The six expeditioners
Gustave
Starts with you and carries Act 1. His Overload is the simplest resource in the game: it builds as he lands hits and you spend it when it is full. He leaves the story at the end of Act 1, so do not sink your rarest Pictos into him.
Lune
The support that is not only a support: she heals and debuffs, which means she is the one who makes long fights survivable while still shaving enemy defences.
Maelle
The party's main damage dealer, and the one most builds end up shaped around.
Verso
Joins early in Act 2. He runs on a Perfection rating that climbs as he lands hits and dodges or parries, and drops when he is hit. High Perfection unlocks extra power on his abilities and raises his damage — so he rewards the player who has already learned the defensive game.
Sciel
Built around her Foretell mechanic; get the most out of it and she is a strong pick rather than a niche one.
Monoco
The last member of Expedition 33 to join, during Act 2.
Three of six
You field three at a time out of the six. Act 1 narrows the choice — Gustave, Lune and Maelle, plus Sciel once she joins at Gestral Village — so the comp question only really opens up once Act 2 has handed you Verso and Monoco.
