The premier free-to-play support in Honkai: Star Rail. The Remembrance Trailblazer (RMC) summons Mem, a memosprite that provides party-wide CRIT DMG buffs, True DMG amplification, and 100% action advance to your carry, all scaling off your CRIT DMG stat.
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.
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.
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.
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.
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.
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.
