Overview of Faction Quests and Targets

Navigating the shifting corridors of the labyrinth requires a deep understanding of the local factions and the entities that reside within. Various organizations, such as the Deici Library, the Hana Association, and the Devyat Association, offer lucrative contracts targeting these anomalous entities. Managing your deck size and selecting the right encounters are key to surviving these hunts.

To optimize your progression, you must align your runs with the requirements of local representatives. The table below outlines the primary quest lines available inside the labyrinth hubs.

Deck Optimization Tip

When working with the Deici Librarian, purge weaker cards early. Keeping your deck at or below 5 cards total ensures you meet the quest requirements while drawing your most powerful combat options consistently.

Abnormality Threat Classifications

To successfully complete the Hana Association research lines, players must hunt down project mirror labyrinth abnormalities across different threat tiers. These tiers dictate the mechanical complexity and damage output of each encounter. Understanding what you are up against prevents sudden squad wipes.

Below is a breakdown of the threat classifications you will encounter, their relative difficulty, and recommended tactical approaches.

WAW-class entities can shred your squad's sanity levels within three turns. Ensure your support characters carry passive healing or sanity restoration before engaging them in the deeper sectors.

ZAYIN Strategy

  • Focus on raw physical damage.
  • Ignore complex setups.
  • Great for fast turn clears.

TETH & HE Tactics

  • Bring defensive shields.
  • Cleanse status effects early.
  • Target weak points systematically.

WAW Management

  • Save burst skills for Phase 2.
  • Maintain high sanity pools.
  • Utilize Devyat passive boosts.

Step-by-Step Hana Research Progression

Unlocking higher research tiers with the LCE Researcher inside the Hana Building is crucial for long-term progression. Follow this structured hunting sequence to complete the research quest efficiently without wasting valuable keys.

1

Locate the LCE Researcher

Travel to the Hana Building and accept the active research contract to begin tracking abnormality signatures.

2

Eliminate ZAYIN Targets

Enter the shallow sectors of the labyrinth to find and neutralize a ZAYIN-class target. This serves as your baseline test.

3

Hunt TETH and HE Entities

Descend to the mid-tier floors. Defeat 5 total TETH or HE abnormalities, focusing on breaking their defensive stances.

4

Confront the WAW Threats

Prepare your optimal 5-card deck setup and challenge 3 WAW-class abnormalities in the deep sectors to finalize your data.

Quest Completion Reward

Finishing the Hana research line significantly boosts your passive drop rates for high-tier E.G.O. fragments throughout the labyrinth.

Devyat Delivery Challenges

The Devyat Association values efficiency above all else. Their contracts demand speed, precision, and the smart application of faction-specific passives. Mastering these challenges unlocks additional delivery slots, which are essential for passive resource generation.

Refer to the checklist below to track your progress through the Devyat representative's requirements.

Devyat Rep Checklist:

  • Clear any labyrinth stage twice using standard setups
  • Equip and activate a Devyat passive skill during a run
  • Complete a full stage clear in less than 20 total turns
  • Claim the permanent +1 Delivery slot reward
Speedrun Strategy

To easily hit the sub-20 turn limit, pair high-damage single-target skills with the Devyat passive's speed buffs. Avoid stalling tactics and focus entirely on offensive pressure.
