Released Jan 15, 2025

Trailblazer (Remembrance · Stelle) GUIDE

Understand Trailblazer (Remembrance · Stelle)

Useful when…

  • Use the Skill to summon Mem, or restore Mem’s HP and grant Charge when it is already on the field.
  • Consider the Ultimate for an all-enemy Ice attack and a direct Charge increase.
  • Consider the Talent when allies regenerate Energy, since their total Energy regeneration grants Mem Charge.

Mem, Charge, and core abilities

The Skill summons Mem if absent. If Mem is already on the field, it restores HP equal to 30% of Mem’s Max HP and grants 10% Charge. The Ultimate summons Mem, grants 40% Charge, then makes Mem deal Ice damage to all enemies equal to 120% of Mem’s ATK. Mem starts with 130 SPD and Max HP equal to 50% of Trailblazer’s Max HP plus 400. The Talent grants Mem 1% Charge for every 10 Energy regenerated by all allies in total. The Basic ATK deals single-target Ice damage based on Trailblazer’s ATK. These are level-one parameters.

Alternate Basic ATK and Technique

The alternate Basic ATK consumes one “Epic” stack, dispels all Crowd Control debuffs on Mem, and has Trailblazer and Mem each deal Ice damage to all enemies based on their respective ATK. Mem then gains 10% Charge. The Technique creates a dimension lasting 10 seconds; enemies within it enter a Time Stop state and halt their actions. When battle begins against enemies in that state, all enemies’ actions are delayed by 50%, then all enemies take Ice damage equal to 1% of Trailblazer’s ATK. Only one ally-created Dimension Effect can exist at a time.

Progression information

The supplied progression lists promotion, levels for the Basic ATK, Skill, Ultimate, and Talent, three bonus ability unlocks, and bonus trace nodes. Their gameplay effects and values are unspecified here, so their relative upgrade value cannot be determined from this information.

Related characters

Caelus is listed as a same-element, same-path Trailblazer comparison candidate. Cyrene and Evernight are also listed with Ice and Remembrance. These shared labels alone do not establish that any of them is a substitute for Stelle.

Limitations and tradeoffs

  • Mem gains Charge through the total Energy regenerated by all allies.
  • The Technique’s Dimension Effect cannot coexist with another ally-created Dimension Effect.
  • The alternate Basic ATK consumes an Epic stack, and how to obtain stacks is unspecified.
  • The supplied progression does not specify the effects or values of bonus abilities and trace nodes.

Common mistakes to avoid

  • Assuming the Skill restores Mem when it is absent; it summons Mem in that case.
  • Assuming the Talent counts only Trailblazer’s Energy regeneration; it counts Energy regenerated by all allies.
  • Using the alternate Basic ATK without accounting for its one Epic stack cost.
  • Assuming the Technique’s Dimension Effect can coexist with another ally-created Dimension Effect.
  • Inferring a general upgrade priority from trace names without supplied effect values.
