Lineage Piece How to Get Saber & Firefly Guide!

Lineage Piece has introduced another major update, bringing two highly anticipated additions to the game: Saber Alter (Excalibur Morgan) and Firefly from Honkai: Star Rail. Both characters come with unique unlock requirements, dedicated mastery quests, and powerful movesets that make them worth pursuing for endgame players. If you’re wondering how to obtain Firefly and Saber Alter, where to find their NPCs, and how to complete their mastery quests efficiently, this guide covers everything you need to know.

How to Get Saber Alter in Lineage Piece

Saber Alter’s seller NPC and mastery NPC can be found on Legends Arena Island. Before unlocking Excalibur Morgan, players must gather several materials from the newly added Ryuudo Cave dungeon.

Step 1: Obtain Ryuudo Keys

To enter the new dungeon, you’ll first need a Ryuudo Key. These keys drop from the regular Saber Boss, which can be summoned on Legends Arena Island. Since multiple dungeon runs are required for both unlock materials and mastery progress, farming extra keys early is highly recommended.

Step 2: Complete the Ryuudo Cave Dungeon

The Ryuudo Cave dungeon consists of three different phases.

Phase One: Defeat Medusa

The first stage requires players to defeat the Medusa boss. Medusa has a chance to drop:

• Servant Covenant
• Saber Alter progression materials
• Additional dungeon rewards

Since Medusa is also part of the mastery requirements later, you’ll likely end up farming this boss multiple times.

Phase Two: Survive the Darkness

The second phase changes the dungeon environment entirely. The screen becomes dark, and players must survive against waves of enemies. You can complete this section by:

• Defeating the mobs
• Avoiding enemies until the phase ends
• Using mobility skills to stay alive

Several enemy types that appear here are needed for Saber Alter’s mastery quests.

Phase Three: Defeat Saber Alter

The final stage features the Saber Alter boss. Most of the materials needed to unlock Excalibur Morgan can be obtained from this encounter, making repeated dungeon runs necessary if you’re aiming to complete both unlock and mastery objectives.

Saber Alter Mastery Requirements

After unlocking Excalibur Morgan, players can begin working on the mastery questline. The complete requirements include:

• Deal 2.5 billion damage using Excalibur Morgan
• Equip the Saber Alter title
• Complete dungeon objectives
• Defeat Medusa 10 times
• Defeat Corruption mobs 50 times
• Defeat Black Ring mobs 50 times
• Die 5 times inside Ryuudo Cave
• Defeat Saber Alter on Extreme Mode 10 times

The quickest method for the 2.5 billion damage requirement is running Simulated Sea, where enemies have enough health to allow rapid damage accumulation. This can dramatically reduce the amount of grinding required compared to farming regular enemies.

Is Saber Alter Worth Unlocking?

Saber Alter comes with flashy abilities, strong AoE attacks, and impressive damage potential. Players looking for a powerful weapon with stylish visual effects will likely enjoy her kit. The mastery grind can take some time, but the overall power and unique animations make the investment worthwhile for many players.

How to Get Firefly in Lineage Piece

The second major addition from this update is Firefly. Her seller NPC is located on Monument Island, where players can begin collecting the required materials. Unlike Saber Alter, Firefly’s progression revolves around several new systems introduced in the update. Two new NPC shops have been added:

• Byte Shop The Byte Shop allows players to purchase Firefly dungeon keys.
• Armor Scrap Shop The Armor Scrap Shop contains several important progression materials, including items required for Firefly’s race evolution and mastery quest.

Both shops play a crucial role in Firefly progression.

How to Get Firefly Dungeon Keys

To access Firefly’s dungeon, players need special dungeon keys. These keys can be purchased from the Byte Shop using Bytes, a currency earned from the Simulated Sea game mode. This means players should spend time farming Simulated Sea before attempting to unlock Firefly.

Firefly’s dungeon functions differently from many previous dungeons. Instead of wave-based progression, players simply need to eliminate enemies.

• At 50 Kills A boss appears after reaching 50 enemy kills. Defeating this boss rewards progression materials needed for Firefly.
• At 100 Kills The final boss spawns after reaching 100 kills. This encounter provides additional rewards and materials required for Firefly’s unlock process.

How to Get the Glamoth Race

One of the update’s new features is the Glamoth Race. To obtain it, players need:

• Glamoth Essence
• Armor Scrap Shop materials
• Dungeon rewards

Because several progression systems overlap, farming Firefly’s dungeon also contributes toward unlocking Glamoth-related content.

Firefly Mastery Guide

After obtaining Firefly, players can start her mastery questline. The mastery NPC can be found near Firefly’s unlock location. Players must complete the following tasks:

• Deal 3.5 billion damage with Firefly
• Equip Firefly’s title
• Use Firefly skills 500 times
• Clear Simulated Sea 5 three times
• Defeat Firefly Type IV enemies 20 times
• Purchase Dreamscape from the Armor Scrap Shop
• Obtain an Oak Cake Roll
• Give the Oak Cake Roll to Firefly

Completing these objectives unlocks Firefly’s full mastery.

The most efficient method involves farming Simulated Sea while selecting cooldown reduction cards. This strategy allows players to spam Firefly’s abilities much more frequently, making the 500-skill requirement significantly faster. An added bonus is that you’ll also progress toward the Simulated Sea completion objective at the same time.

Is Firefly Worth Getting?

Among the two additions in this update, Firefly is arguably the most sought-after. Her moveset features impressive visual effects, powerful attacks, and excellent overall performance.

Many players consider Firefly one of the strongest and most stylish characters introduced to Lineage Piece so far. Combined with the Glamoth Race progression system, she offers substantial value for players looking to strengthen their account.

The latest Lineage Piece update adds a substantial amount of content through Saber Alter, Firefly, the Glamoth Race, Ryuudo Cave, and the expanded Simulated Sea progression system. While both unlock paths require considerable grinding, the rewards are among the strongest additions currently available in the game.

For players deciding where to invest their time first, Firefly will likely be the higher priority due to her powerful abilities and overall utility. However, Saber Alter’s Excalibur Morgan remains an excellent choice for those seeking a high-damage weapon with an impressive mastery progression system.

With efficient farming and smart use of Simulated Sea, unlocking and mastering both additions can be completed much faster than many players expect.
