Lost Sword Tier List: Best Heroes to Build First

To progress efficiently through campaign stages, Abyss floors, and boss raids in Lost Sword, focus your early upgrade materials on high-scaling damage carries and universal buffers before investing in specialized counters.

The most reliable core heroes are Elizabeth for boss burst damage, Flame Emperor for frontline wave clearing, and Eva for party-wide energy generation and attack amplification.

Character Breakdown and Tactical Roles

S-Tier: Core Progression Anchors

Elizabeth: Serves as the primary single-target carry. Her multi-hit skill rotations scale heavily with critical hit rate, making her the top option for burning down high-health raid and Abyss targets.
Flame Emperor: Acts as an offensive tank. His durability allows him to absorb frontline pressure while his area-of-effect fire damage quickly clears secondary enemy waves.
Eva: Provides team-wide attack buffs, healing, and energy recovery. Eva accelerates your primary carry's ultimate availability, making her effective across all stage types.

A-Tier: High-Impact Specialists

Guinevere: Stabilizes runs where backline units face sudden burst damage. Her shields and threat generation protect fragile damage dealers from dive mechanics.
Lucius: Best deployed alongside physical carries like Elizabeth. His defensive shred weakens high-armor frontline targets.
Merlin: Delays incoming enemy abilities with freeze and slow effects, buying time for your main carry to build energy.

B-Tier: Tech Choices

Units in B-tier provide narrow mechanical utility, such as dispelling enemy barriers or applying anti-heal. Treat these heroes as situational substitutes rather than primary resource sinks.

Standard Four-Hero Team Formation

Assemble your team using one frontline anchor, one dedicated carry, one debuffer or crowd-controller, and one support:

Frontline Anchor: Flame Emperor (for damage and wave clear) or Guinevere (for pure defensive stabilization)
Primary Carry: Elizabeth
Secondary Utility / Debuffer: Lucius (for armor shred) or Merlin (for mob control)
Support: Eva

Pairing Elizabeth with Eva ensures Elizabeth triggers her ultimate ability repeatedly before stage enrage timers expire. If your backline dies too quickly, replace your secondary damage dealer with Guinevere to absorb incoming damage.

Investment Priority Order

To avoid spreading materials too thin, allocate resources in the following order:

Max Elizabeth's Level and Weapons First: Funnel experience materials, duplicate weapon copies, and critical-rate gear into your primary carry until she reaches your account's level cap.
Reinforce Your Frontline Tank: Upgrade armor, defensive relics, and health passives on Flame Emperor or Guinevere to prevent frontline collapses.
Level Up Eva's Active Skills: Focus on skill scrolls for Eva’s attack and energy-generation abilities. Supports do not need top-tier offensive gear to provide their core team value.
Hold B-Tier Promotions: Avoid spending universal skill books or high-tier relic materials on situational units until your primary four-hero team is fully leveled.
