Character Rankings Overview

The hierarchy below evaluates Trekkers by versatility in PvE and competitive scenarios. While 5-star units typically surpass 4-star counterparts, numerous lower-rarity options remain essential for exploiting elemental matchups. Prioritization depends on synergy with team compositions and target content.

Significant 4-Star Picks

Notable combatants include Flora, Ann, Cosette, Tilia, and Ridge, offering exceptional damage output or team support capabilities.

Elite 5-Star Units

Dominant choices feature Nanoha, Minova, Nazuna, Gerie, and Chitose—the latter being a time-limited unit with unparalleled battlefield impact.

Mid-Tier Specialists

Even lower-ranked fighters maintain viability when aligned with elemental strategies or niche scenarios.

Strategic Insights

Earth-aligned teams currently dominate due to universally strong Trekkers. Water compositions also excel with dual top-tier 5-star options.

Reroll Targets

Prioritize acquiring Chitose during initial pulls, followed by Gerie, Nazuna, or Minova for balanced rosters.

Mid-Tier Utility

Lower-ranked units remain crucial for overcoming elemental barriers in story stages and specialized challenges.
