This team composition guide is mainly for PvE progression and doesn't factor in PvP strength. In the early game, when you don't have many hero options, it's a good idea to build teams that meet elemental affinity conditions rather than forcing specific damage compositions. Early on, you can quickly get items to upgrade your Player Character's skill level. The Player Character can switch between three different elements with shared skill levels, only needing some Elemental Gems for development. This provides excellent Battle Capacity during the exploration phase.
Wildfire
Ice-Necrosis
Offers strong AoE capabilities early on; but it's relatively weak against single-target Bosses.
Light-Electric (Highly Recommended)
Altair boasts incredibly high damage and truly shines in single-target boss fights. When the Dauntless comp pool rolls around, try to snag Silver Moon Sentinel while also getting Nastjenka. This will seriously amp up your team's overall power. Altair + Silver Moon Sentinel can practically solo most PvE dungeons, while Nastjenka helps smooth out the team's PvP weaknesses, making your progress much easier.
