Lineage Piece Cid Quest Overview

The Lineage Piece Cid quest is a major progression milestone added during the Eminence in Shadow update. This questline revolves around unlocking the Shadow fighting style, a powerful and visually impressive moveset inspired by Cid Kagenou. To access this content, players must first obtain the Stylish Bandit Beater, complete a series of combat challenges, and conquer the Sid raid dungeon.

The questline is structured into several distinct phases, each requiring specific actions and locations. Players will travel from Starter Island to Frost Island and eventually into the Sid dungeon. The rewards include the Shadow fighting style, unique race buffs, and access to the Atomic ability.

Preparation Checklist

Before starting the Cid questline, ensure your character is adequately leveled and geared. The Sid raid on medium difficulty or higher requires a solid build to survive all 10 waves and defeat both bosses.

Phase 1: Stylish Bandit Beater Questline

The Stylish Bandit Beater serves as the entry point for the entire Cid questline. Without this weapon, the Shadow Seller NPC on Frost Island will not offer any quests. The questline takes place on Starter Island and involves a straightforward but mandatory series of tasks.

Step 1: Find Two Crowbars

ItemLocationDifficulty
Crowbar 1Starter Island (west side)Easy
Crowbar 2Starter Island (east cliffs)Easy

Both crowbars are hidden on Starter Island. Search the west side and the eastern cliff areas to locate them. Once collected, return to the quest NPC to proceed to the next step.

Step 2: Take 5 Million Damage

The second requirement is to absorb 5 million damage. The most efficient method involves traveling to Scorched Ruins and crafting a Trial Key. Enter the nightmare difficulty trial and allow the mobs to attack your character repeatedly.

Damage Farming Tip

For faster damage absorption, intentionally lose to the wave 2 or wave 3 boss in the Scorched Ruins nightmare trial. The boss attacks deal significantly more damage than regular mobs, cutting down the total time required.

Step 3: Purchase the Stylish Bandit Beater

After completing both tasks, the ability to purchase the Stylish Bandit Beater unlocks. Equip it immediately, as it is required for every subsequent step in the Cid questline.

Phase 2: Shadow Questline on Frost Island

With the Stylish Bandit Beater equipped, travel to Frost Island and locate the Shadow Seller NPC. This NPC manages the core Cid questline and offers the quests needed to unlock the Shadow fighting style.

Quest Breakdown

QuestRequirementRecommended Strategy
Kill 250 MobsDefeat 250 enemies with Stylish Bandit BeaterGrind in high-density mob zones
Sid Raid x5Complete Sid raid on medium or higherForm a party for consistent clears
Collect Sid DropsObtain items dropped by Sid bossFocus damage on Sid in final waves

The first quest requires killing 250 mobs exclusively with the Stylish Bandit Beater. This can be time-consuming, so target areas with fast respawn rates and high enemy density. Switching weapons during this quest will not count kills toward the total.

Efficient Mob Grinding

Choose zones where mobs respawn quickly and have low health. The goal is volume, not difficulty. Avoid elite zones that slow down your kill rate.

Sid Raid Dungeon

Once the Stylish Bandit Beater questline is complete, Sid keys begin dropping. These keys teleport players to the Sid dungeon, which features 10 total waves and two bosses: Alpha and Sid.

Boss: Alpha

  • Appears in mid-waves
  • High aggression
  • Requires strong defense
  • Drops Sid-related materials

Boss: Sid

  • Final wave encounter
  • Complex attack patterns
  • Drops Shadow quest items
  • Must defeat on medium+ difficulty
Raid Completion

After completing five Sid raid clears on medium or higher difficulty and collecting all required Sid drops, return to the Shadow Seller NPC on Frost Island to purchase the Shadow fighting style and unlock Atomic.

Shadow Moveset and Mastery

After unlocking the Shadow fighting style, players gain access to a dynamic and visually striking moveset. The Shadow style features smooth animations, strong damage output, and impressive visual effects that make it one of the standout fighting styles in the game.

Unlocking the Arm Move

To unlock the arm move for the Shadow style, visit the mastery NPC. The requirements are displayed on-screen and typically involve additional materials and currency investment.

The Shadow moveset performs well in damage tests, offering solid DPS with smooth combo transitions. The visual effects are notably polished compared to many other fighting styles in the game.

Eminence in Shadow Race Buffs

The update also introduces race-specific buffs tied to the Eminence in Shadow theme. These buffs provide additional stat bonuses that complement the Shadow fighting style, making it even more effective in both PvE and raid scenarios.
