Skills

Basic Leave It to Me!

Deals Ice DMG equal to 50% of Trailblazer's ATK to one designated enemy. Low priority in combat since using the Skill or Enhanced Basic is almost always better, but it generates Mem's Charge passively through the Talent.

50% of ATK
Skill I Choose You!

Summons the memosprite Mem. If Mem is already on the field, restores Mem's HP by an amount equal to 30% of Mem's Max HP and grants Mem 10% Charge. Your primary tool for keeping Mem alive and charging her early.

30% Mem HP restore
Ultimate Together, Mem!

Summons memosprite Mem. Grants Mem 40% Charge, then enables Mem to deal Ice DMG equal to 120% of Mem's ATK to all enemies. Using the Ultimate right before Mem reaches 100% Charge is the core way to trigger her action-advance immediately.

120% Mem ATK, AoE
Talent Almighty Companion

Memosprite Mem has an initial SPD of 130 and Max HP equal to 50% of Trailblazer's Max HP plus 400. For every 10 Energy regenerated by all allies in total, Mem gains 1% Charge. Mem's Memosprite Talent (Friends! Together!) buffs all allies' CRIT DMG by 6% of Mem's CRIT DMG plus 12%, making your CRIT DMG stat directly amplify the whole team.

1% per 10 Energy
Technique Memories Back as Echoes

After using Technique, creates a Special Dimension lasting 10 seconds. Enemies within are placed in a Time Stop state, halting all actions. Upon entering battle, delays all enemies' actions by 50% and deals Ice DMG equal to 100% of Trailblazer's ATK to all enemies. Only 1 Dimension Effect from allies can exist simultaneously.

50% enemy delay

Best Light Cones

#1
Long May Rainbows Adorn the Sky
Long May Rainbows Adorn the Sky
Best-in-slot. Provides a significant SPD boost and increases the damage taken by enemies, very effective on Castorice and Blade teams where the debuff synergizes with high-damage carries. Note the debuff does not stack if multiple allies equip it.

World-Remaking Deliverer
World-Remaking Deliverer
Best-in-slot cavern set. The 4-piece bonus increases the Trailblazer's Max HP and allows them to boost the DMG of all allies while Mem is on the field. Directly synergizes with the role of keeping Mem active as much as possible.

Best Teams for Trailblazer (Ice)

Trailblazer (Ice) works best with DPS characters who have high Ultimate energy costs (100+). The Magnets and Long Chains trace increases the True DMG multiplier of Mem's Support by 2% for every 10 excess energy above 100, up to a maximum increase of 20%. Pair with energy-restoring supports to fill Mem's Charge quickly.

Eidolons

E 1
Narrator of the Present
Increases the CRIT Rate of the ally target with "Mem's Support" by 10%. When an ally target has Mem's Support, its effect also takes effect on that target's memosprite or memomaster. This effect cannot stack. Strong pick-up that immediately benefits your main DPS with a free CRIT Rate boost every time Mem acts.
High Pull Value
E 2
Gleaner of the Past
When ally memosprites (aside from Mem) take action, Trailblazer regenerates 8 Energy. Triggers a maximum of 1 time per turn; resets at the start of the Trailblazer's turn. Essential for Remembrance team compositions where allied memosprites act frequently, massively accelerating Mem's Charge refill loop.
Remembrance Game Changer
E 3
Chanter of the Future
Skill Lv. +2 (max 15). Talent Lv. +2 (max 15). Memosprite Talent Lv. +1 (max 10). The Talent and Memosprite Talent level increases provide meaningful improvements to Mem's CRIT DMG buff output.
Solid Upgrade
E 4
Dancer of the Muse
When an ally target with 0 Max Energy (like Feixiao or Acheron at E2) uses an ability, Mem gains 3% Charge, and the True DMG multiplier of Mem's Support for that target additionally increases by 6%. Pairs very well with zero-energy carries who have frequent action usage.
Niche Value
E 5
Seamster of the Ode
Ultimate Lv. +2 (max 15). Basic ATK Lv. +1 (max 10). Memosprite Skill Lv. +1 (max 10). Incremental improvements across multiple abilities. Useful but not transformative on its own.
Incremental
E 6
Bearer of the Revelation
The Ultimate's CRIT Rate is set at 100%. Guarantees every Together, Mem! ultimate crits, improving the Trailblazer's own damage output from the AoE hit. A meaningful DPS improvement for the Trailblazer themselves.
DMG Boost

Major Traces

Rhapsode's Scepter
Ascension 2
When battle starts, Trailblazer's action advances by 30%. When Mem is first summoned, additionally grants Mem 40% Charge. Allows the Trailblazer to move at the very front of the turn order in most cases and ensures Mem starts combat with a strong Charge lead.
Petite Parable
Ascension 4
When using Mem's "Baddies! Trouble!" attack, Mem immediately gains 5% Charge. Every auto-attack Mem makes between full-Charge actions adds a small but meaningful amount of Charge, accelerating the cycle.
Magnets and Long Chains
Ascension 6
When the Max Energy of the ally target with "Mem's Support" exceeds 100, for every 10 excess Energy, additionally increases the True DMG multiplier by 2%, up to a maximum increase of 20%. The core reason to pair RMC with high-energy-cost carries like Argenti (180 Energy) or The Herta.

Frequently Asked Questions

No. Trailblazer (Ice) performs strongly with free options like Fly Into a Pink Tomorrow and Victory in a Blink. Long May Rainbows Adorn the Sky is a meaningful upgrade, particularly on Castorice and Blade teams, but is not required to clear all endgame content at E0.
Mem gains 1% Charge for every 10 Energy regenerated by all allies in total. Using the Trailblazer's Skill adds 10% Charge, and using the Ultimate adds 40% Charge. When Mem's Charge reaches 100%, Mem immediately takes an action and can select one ally to use "Lemme! Help You!", advancing that ally's action by 100% and granting them "Mem's Support," which causes Mem to deal True DMG for every instance of DMG that ally deals. Planning when Mem hits 100% relative to your DPS's turn is the core skill expression of this kit.
The Ascension 6 trace (Magnets and Long Chains) increases the True DMG multiplier by 2% for every 10 Energy above 100 that the supported ally has, up to a maximum of 20% extra multiplier. A character with 180 Energy (like Argenti) gets the full 20% bonus, whereas a character with exactly 100 Energy gets no bonus. This makes high-energy carries like Argenti, The Herta, Castorice, Mydei, and Jingliu significantly stronger partners for this version of Trailblazer.
Aim for 160 SPD. This allows Trailblazer (Ice) to summon Mem at the very start of the turn order before enemies act, which lets Mem accumulate Charge from enemy attacks landing on your team. The Ascension 2 trace already advances the Trailblazer's initial action by 30%, helping hit this breakpoint more consistently. Sprightly Vonwacq further advances their action at the start of battle.
Yes, Trailblazer (Ice) is rated S+ in both Memory of Chaos and Pure Fiction. The True DMG buff and action advance work universally across all endgame content. In Pure Fiction, pairing with The Herta or Jade allows the AoE attacks to benefit from the True DMG amplification. In Apocalyptic Shadow, pairing with single-target burst carries like Castorice or Mydei is highly effective.
E1 and E2 are the most impactful. E1 grants 10% CRIT Rate to the Mem-supported ally and extends the buff to their memosprite or memomaster, immediately useful in almost all teams. E2 is a game changer for Remembrance team compositions, where allied memosprites taking action recharges the Trailblazer's energy (8 Energy per memosprite action, once per turn), dramatically accelerating the Mem Charge loop. E4 has niche value for zero-energy carries like Feixiao or Acheron (at E2).
