Firefly Overview & Update Highlights

The latest Lineage Piece update introduces Firefly, bringing a fresh combat style and new progression systems to the game. Alongside Saber Alter, Firefly represents a significant power creep and introduces unique mechanics like the Glamoth race and new farming currencies.

Video Highlights:

  • Firefly seller NPC is located on Monument Island
  • Dungeon keys are purchased using Bites from the Bite Shop
  • Simulated C game mode is the primary source for farming Bites
  • New Glamoth race requires Glamoth essence from the Armor Scrap Shop
  • Mastery involves dealing 3.5 billion damage and completing specific combat trials

The update expands the endgame content considerably. Players now have access to two new shop NPCs—the Bite Shop and the Armor Scrap Shop—both essential for crafting and unlocking Firefly's full potential. The dungeon format for Firefly differs from traditional wave-based encounters, focusing instead on reaching specific kill counts to trigger boss spawns.

Preparation Advice

Before attempting the Firefly dungeon, ensure your character is adequately geared for sustained mob clearing. The dungeon requires 100 total kills to spawn the final boss, meaning consistent AoE damage output is essential for efficient clears.

Unlock Requirements & Material Farming

Acquiring Firefly involves multiple steps, from gathering currencies to clearing her dedicated dungeon. The process is straightforward but requires dedicated farming time in specific game modes.

1

Travel to Monument Island

Locate the Firefly seller NPC on Monument Island. Interact with the NPC to view the full list of unlock requirements and necessary materials.

2

Farm Bites in Simulated C

Enter the Simulated C game mode and complete runs to accumulate Bites. This currency is the primary gate for accessing Firefly's dungeon content.

3

Purchase Dungeon Keys

Visit the Bite Shop NPC and exchange your farmed Bites for Firefly dungeon keys. Stock up on multiple keys to avoid repeated trips.

4

Clear the Firefly Dungeon

Enter the dungeon and defeat mobs until you reach 50 kills to spawn the first boss. Continue to 100 kills to trigger the final boss encounter.

5

Collect Glamoth Essence

Visit the Armor Scrap Shop to obtain Glamoth essence. This material is required to unlock the new Glamoth race associated with Firefly.

Dungeon Mechanics

The Firefly dungeon has no traditional waves. You must kill mobs continuously—at 50 kills, a mini-boss spawns, and at 100 kills, the final boss appears. Both bosses drop essential materials for unlocking Firefly.

Firefly Mastery Questline

Once Firefly is unlocked, the mastery questline becomes available from a dedicated NPC. Completing these quests is critical for maximizing her combat effectiveness and unlocking her full skill potential.

Efficiency Trick

Combine quests 3 and 4 by running Simulated C5 while selecting cooldown cards. This lets you rack up the 500 skill uses and clear the stage three times simultaneously, saving significant farming time.

The most time-consuming quest is dealing 3.5 billion damage. Simulated C5 is the recommended location because the enemies there have sufficient health pools to make damage accumulation efficient. Bring your strongest damage-boosting gear and focus on maximizing DPS output during each run.

For the skill usage quest, the cooldown card strategy in Simulated C mode is the fastest known method. Prioritize cards that reduce skill cooldowns to near-zero, allowing you to spam abilities rapidly and complete the 500-use requirement in a single extended session.

Firefly Combat Showcase & Moveset

Firefly brings a visually striking and mechanically satisfying moveset to Lineage Piece. Her kit emphasizes aggressive close-range combat with powerful burst damage options.

Burst Damage

  • High single-target DPS
  • Excels against bosses
  • Strong ultimate ability
  • Ideal for dungeon phases

Mobility

  • Engaging move set
  • Quick repositioning tools
  • Effective for mob clearing
  • Sustained combat presence

Utility

  • Glamoth race synergy
  • Dreamscape enhancement
  • Title-based stat boosts
  • Flexible build options

The damage test results confirm that Firefly ranks among the top characters in the current meta. Her ability to consistently output high damage while maintaining mobility makes her a strong pick for both dungeon clearing and boss encounters.

Build Recommendation

Pair Firefly with cooldown reduction gear and damage-boosting titles to maximize her effectiveness. The Dreamscape item from the Armor Scrap Shop provides additional stats that complement her aggressive playstyle.
