The Remembrance Trailblazer is an Ice-element character whose kit revolves around their memosprite summon, Mem. As a versatile support unit, they can boost the team’s Crit DMG and, through Mem’s Support ability, grant a selected ally immediate action. That ally also deals True DMG with all their attacks for 3 turns. Mem’s Support is activated by consuming Charge—a stacking resource generated through several methods, including the Trailblazer’s Skill, Ultimate, their 4th Eidolon effect, and most notably, when allies regenerate energy.
Best Cavern Relics
(2) Increases ATK by 12%.
(4) While the wearer's memosprite is on the field, increases the wearer's SPD by 6%. When the wearer's memosprite attacks, increases the wearer's and memosprite's CRIT DMG by 30%, lasting for 2 turn(s).
As a straightforward Cavern Relic set that synergizes with the Memosprite, this set allows the Trailblazer to fully maximize its Crit DMG buff simply by having Mem deal damage. In turn, this further enhances the Crit DMG buff that Mem provides to the team.
Best Planar Ornaments
(2) Increases the wearer's Energy Regeneration Rate by 5%. When the wearer's SPD reaches 120 or higher, the wearer's action is Advanced Forward by 40% immediately upon entering battle.
Since Mem doesn't appear immediately at the start of battle, equipping the Sprightly Vonwacq Planar Ornament helps the Trailblazer act first, increasing their chances of summoning Mem early.
(2) Increases the wearer's Effect RES by 10%. When the wearer's Effect RES is at 30% or higher, all allies' CRIT DMG increases by 10%.
This set is partially effective for the Trailblazer, as it provides a team-wide Crit DMG boost that synergizes well with Mem’s own Crit DMG buffing capabilities.

info
Prioritizing the Trailblazer’s Crit DMG is the most effective approach, as their initial Crit DMG buff activates at the start of battle and can be further amplified by relic effects over time. Speed should be the next priority to ensure faster turns, followed by Energy Regeneration Rate to maintain consistent Ultimate uptime. Equipping HP% or DEF% stats also helps improve survivability against incoming attacks.
While the Trailblazer’s personal damage output is modest, their Ultimate serves a key support role by restoring 40% of Mem’s Charge. Additionally, it can inflict Weakness Break—delaying enemy turns when triggered—which adds valuable utility to their kit.
Best Light Cones
SourceLight Cone Event Warp
Tolerant
Increases the wearer's SPD by 18~30%. When the wearer uses Basic ATK, Skill, or Ultimate, consumes all allies' HP equal to 1.0~2.0% of their current HP and additionally deals 1 instance of Additional DMG of the wearer's memosprite Type equal to 250.0~500.0% of the total consumed HP to the attacked target after the next attack launched by the wearer's memosprite. The total HP consumed is then reset. When the wearer's memosprite uses Memosprite Skill, increases the DMG taken by all enemies by 18.0~36.0% for 2 turn(s). The same types of effects cannot stack.Considered their best Light Cone, it increases the DMG taken by all enemies for 2 turns—significantly boosting the team’s overall DPS output.
Reception
Increases the wearer's SPD by 6~12%. After the wearer uses Skill, increases the DMG dealt by all allies by 8~16%, lasting for 3 turn(s).Similar to their best Light Cone, this one also provides solid damage enhancement through a team-wide DMG buff. While its Superimposition 5 (S5) effect may fall slightly short of Long May Rainbows Adorn the Sky at Superimposition 1 (S1), it lasts one turn longer—offering improved Skill Point management and more sustained team support.

Final Hit
Increases the wearer's CRIT DMG by 12~24%. When the wearer's memosprite uses an ability on an ally target, increases the DMG dealt by all ally targets by 8~16%, lasting for 3 turn(s).This Light Cone is considered their best 4★ option, offering a reliable team-wide DMG boost. Its effect is triggered by Mem’s Crit DMG buff at the start of battle, making it a natural fit for the Trailblazer’s kit.
