Trailblazer • Preservation — Honkai Star Rail Character Guide

Overview

DEF-scaling sustain with party-wide shields on every action, AoE taunt, and 15% teamwide DMG reduction from Skill. Only endgame value in Acheron Trend teams; outclassed by premium sustains in late-game content.

DEF-scaling Preservation sustain who provides party-wide shields on every action (Basic, Skill, Ultimate) via Talent. Manages Magma Will stacks (gained when hit or via Skill/Basic) to unlock Enhanced Basic ATK as a Blast AoE. Skill taunts all enemies with 100% base chance and grants 50% personal DMG Reduction. Ultimate deals AoE Fire DMG scaling with ATK and DEF, and grants a free Enhanced Basic. Primary value is consistent shield upkeep and AoE taunt for redirecting damage.

Key Mechanics

• Shields from Talent are small (6% DEF + 80 at max Talent, roughly 260 HP at 3000 DEF) but refresh on every action. They mitigate chip damage and multi-hit attacks effectively but cannot absorb full late-game enemy attacks.
• Taunt requires Skill every turn (SP negative). The 100% base chance needs Effect Hit Rate investment (30%+) to reliably succeed against higher-level enemies with innate debuff resistance.
• Primary late-game value is in Acheron teams when equipped with Trend of the Universal Market LC — the Burn applied when hit generates Acheron Ultimate charges. The taunt ensures consistent hit-taking for debuff generation.
• All eidolons are obtained for free through gameplay progression. E6 (+30% DEF stacking) and E2 (+2% DEF + 27 shield value) are the most impactful for shield scaling.

Trailblazer • Preservation Investment Priority

1. E6 — Only meaningful stopping point — adds up to 30% DEF stacking from Enhanced Basics and Ultimate, visibly improving shield strength. Still insufficient for solo sustain in late game but the only eidolon that noticeably changes performance.
2. LC S5 — Moment of Victory S5 or Trend S5 depending on context — Trend S5 specifically for Acheron teams where debuff generation is the primary value.
3. E2 — Marginal shield improvement (2% DEF + 27 extra per shield application), worthwhile if already at E2 from exploration but not worth targeting.

Trailblazer • Preservation Relics and Stat Targets

Best Trailblazer • Preservation Light Cones

• Moment of Victory (Best in Slot): Best general-use LC. Provides permanent increased aggro (passive taunt effect), 24% DEF at S1 scaling to 40% at S5, and a conditional +24–40% DEF bonus for 1 turn when hit. Since Fire TB uses Skill to taunt enemies and gets hit frequently, both the passive aggro and the reactive DEF buff trigger consistently, maximizing shield scaling.
• Trend of the Universal Market: Specialist LC for Acheron teams. Provides 16–32% DEF and applies Burn to enemies on hit with 100–120% base chance. Each Burn instance generates 1 Acheron charge per turn (2 with Jiaoqiu E1). Fire TB's Skill-based taunt ensures they are hit every round, generating consistent debuff stacks. This is the primary reason to use Fire TB in late-game content.
• Landau's Choice: Reliable F2P taunt option. Increases aggro and reduces DMG taken by 16% at S1 up to 24% at S5. Trades the DEF stacking of Moment of Victory for flat DMG reduction, making it more consistent against burst damage. Best early-game LC when Moment of Victory is unavailable.
• Texture of Memories: Survival-focused option providing 8–16% Effect RES and emergency HP restoration (16–32% Max HP shield when hit with no shield active, once every 3 turns). Also reduces DMG taken by 12–24% when shielded. Lacks the taunt effect of Moment or Landau, so enemies may not consistently target Fire TB. Use only when debuff immunity is needed and taunt from relics covers aggro.

Important Notes

• Harmony Trailblazer is a vastly superior long-term investment — prioritize them over Fire TB for any end-game consideration.
• Shield values are too small for late-game content — enemy attacks deal thousands of damage while shields absorb 200–400 HP at realistic DEF values.
• Taunt requires SP every turn (SP-negative), and the 100% base chance still needs EHR investment to reliably succeed against later-game enemies.
• Cannot solo-sustain most Memory of Chaos or Apocalyptic Shadow content — shields do not fully mitigate enemy attacks even at E6.
• All premium sustains (Aventurine, Lingsha, Huohuo, Fu Xuan, Luocha, Gallagher) outperform Fire TB in survivability and offensive contribution in late-game scenarios.
