Trailblazer • Remembrance — Honkai Star Rail Character Guide

Overview

Universal support with memosprite Mem providing True DMG amplification, party-wide CRIT DMG buffs, and 100% Action Advance. True DMG acts as final damage multiplier (1.28x base, up to 1.48x with high Energy DPS), making them effective across all archetypes including Break, DoT, and traditional damage.

Remembrance support who summons the memosprite Mem, providing a permanent party-wide CRIT DMG buff, 100% Action Advance to a chosen ally, and a True DMG multiplier (Mem's Support) that amplifies all damage types as a final multiplier. Manages Mem's Charge gauge — fueled by total ally Energy regeneration — to cycle between AoE attacks (below 100% Charge) and single-target support buffs (at 100% Charge). SP positive in practice since the Trailblazer mostly uses Basic ATK after Mem is summoned.

Key Mechanics

• Mem's Support True DMG acts as a final damage multiplier — it takes the final calculated damage of each instance and adds a True DMG copy equal to 28% (base) of that amount. Because it mirrors final damage, it multiplicatively benefits from all existing buffs, debuffs, DEF shred, and RES PEN already applied. Works on all damage types: raw DMG, Break DMG, Super Break DMG, DoT DMG.
• Mem copies the Trailblazer's pre-combat stats only. Conditional buffs from relics or light cones that activate during combat do NOT retroactively apply to Mem. The World-Remaking Deliverer 4pc explicitly states it applies to the memosprite, making it an exception.
• Mem's Support can be active on multiple allies simultaneously — the buff lasts 3 turns per target and is not limited to one recipient. Fast Charge cycling can maintain the buff on two allies at once.
• The 100% Action Advance from Mem's Support triggers immediately when Charge reaches 100% and cannot be delayed or held. Players must manage Charge timing to avoid advancing allies at suboptimal moments. Holding the Trailblazer's Ultimate is one way to control timing, but risks wasting Energy.
• Mem is a targetable entity that can be attacked and defeated. When Mem falls, Trailblazer's action advances by 25% (from passive). Mem must be resummoned via Skill or Ultimate, costing 1 SP and a turn.

Investment Priority

1. E1 — Enables Mem's Support to buff both master and memosprite simultaneously in Remembrance teams. Without E1, users must choose between buffing the DPS or their summon.
2. E2 — When ally memosprites act, Trailblazer regenerates 8 Energy per turn. Significant in multi-Remembrance teams (16+ Energy per cycle), accelerating Ultimate uptime and Mem's Charge generation.
3. LC S1 — SPD breakpoint enables fast rotations. Signature provides CRIT DMG and team DMG buff, but gap to alternatives (Memory's Curtain) is manageable.

Important Notes

• Mem's Action Advance triggers immediately at 100% Charge and cannot be delayed — can disrupt optimal rotation timing
• Mem is a targetable unit and can be defeated by enemy attacks, requiring resummon via Skill or Ultimate
• Using Remembrance Trailblazer locks you out of Harmony Trailblazer (cannot use both simultaneously)
• Mem copies pre-combat stats only — conditional buffs from relics/light cones that activate during combat do not apply to Mem
• Mem's Support can only be used on one ally at a time (though 3-turn duration allows buffing multiple allies in sequence)
• E1 synergy with Remembrance characters is significant — consider if you plan to use non-Remembrance teams
