Limbus Company 9th Walpurgisnacht Complete Guide: Mechanic Breakdown, Solo Clear Cheese, and New Tremor & Sinking Team Meta Shifts


Dawn Office Assembles, Tremor Teams Receive an Epic Upgrade
The ninth Walpurgis Night officially started on July 9 and runs until July 23. The biggest highlights this time are clear: the full Dawn Office trio has finally arrived, Solemn Lament Yi Sang E.G.O brings a fundamental upgrade to the Tremor system, and the solo cheese strategy for difficult missions remains reliable.
For veteran players, this Walpurgis Night is not just about pulling new characters. It is also a key moment where Tremor/Sinking teams receive major reinforcements. Below, we will break everything down from four angles: mechanics, missions, solo clears, and team building.
【1. Enemy Mechanics: Weak to Pierce and Wrath, Double Damage When Unopposed】
Based on patterns from previous Walpurgis Nights and current testing, enemies have several key traits:
The three major weaknesses:
Pierce — the most effective damage type
Wrath — provides a high damage bonus
Gloom — also benefits fully from weakness bonuses
Core mechanics:
Enemies have Unbreakable Coins
Unopposed attacks deal double damage
What does this mean? Instead of forcing clashes, it is much more efficient to use high-damage Identities for Unopposed attacks. This is not just theorycrafting; the community has already tested it multiple times. Picking the right attributes and bursting enemies down is simply the most practical approach.
【2. New Identities and E.G.O: Who Wins This Version?】
The Dawn Office trio
The biggest structural change in this Walpurgis Night is the official assembly of the Dawn Office trio:
Dawn Office Fixer Faust: The community rates her as “the strongest unit in this Walpurgis Night, with fast ramp-up, assist attacks, Coin reuse on Skills 1/2/3, and strong damage across all skills once warmed up.” She challenges Mao Faust’s position in Tremor teams, because Dawn Office Faust also comes with Speed increase effects and better fits the tempo of Tremor setups.
Dawn Office Rep Gregor: A strong fire-based Identity with excellent stats. The damage on the final Coin of his enhanced Skill 3 is considered “ridiculously over the top,” and the animation is stylish as well. Some players who tested him simply described him as “insanely strong.”
Dawn Office Fixer Sinclair: The biggest beneficiary of this Walpurgis Night, jokingly said to have “eaten eight new buffs for free.” According to community breakdowns, Sinclair needs both Gregor and Faust to reach full power — Gregor activates “ScorchField,” while Faust allows Sinclair to consume that effect to enhance “Blazing Strike.”
Solemn Lament Yi Sang E.G.O: The Key to Tremor Team Transformation
The truly far-reaching addition this time is Yi Sang’s new E.G.O, “Solemn Lament.”
Why is this important? Because it directly changes the construction logic of Tremor teams. Yi Sang’s E.G.O effect grants the Tremor keyword to “Butterfly Yi Sang” (Ring Yi Sang), allowing Tremor and Sinking Identities to be included in the same six-person team. In other words, the old situation where players had to choose either “Tremor” or “Sinking” has been broken. Now the two can coexist and strengthen each other.
According to detailed analysis from Korean guide sites, this change makes Tremor/Sinking teams — often shortened to “Tremor-Sinking teams” — much more flexible, while also giving newer players a clearer path to assembling the required pieces. For veteran players, it means another stable solution for high-difficulty stages.
【3. Difficult Mission Cheese: Ring Yi Sang Solo Is Still the Answer】
The core cheese strategy for Walpurgis Night difficult missions is still soloing with Ring Yi Sang.
Why Yi Sang?
● His skills naturally include Pierce/Wrath/Gloom damage, perfectly matching enemy weaknesses
● Skill 3 deals enough damage to instantly kill small enemies
● IRA can heal him, improving consistency
● Furioso E.G.O can reliably secure three kills
The operation flow is very fixed:
1: Use Evade during the first few turns to avoid damage
2: Use powerful skills for Unopposed attacks
3: If HP is low, activate IRA to heal
4: When three small enemies appear on the field, use Furioso directly to complete the triple-kill mission
If the mission requires killing a specific target, such as a Training Unit Captain, remember to place the Identity responsible for the kill in the leader slot.
However, there are two things to note: if you do not have the new Solemn Lament Yi Sang from this Walpurgis Night, using only Ring Yi Sang may get stuck on certain special missions, such as applying eight different debuffs in a single turn. This task requires combining effects such as Bleed, Sinking, Tremor, Nails, Burn, Clash Power Down, and Speed Down to reach eight types, and veteran players widely consider it a real technical check.
One player’s test result was: “Butterfly Yi Sang still gives a lot of butterflies himself. Constantly using his ultimate will reduce SP, which can make him start trolling himself... but his numbers are high, his colors are good, and the solo experience feels pretty smooth.”
Other characters capable of solo clears:
Dawn Office Faust: Already verified to solo high-difficulty content
Lobotomy Corporation E.G.O: Solemn Lament Yi Sang: Can also clear Hard Mirror Dungeon consistently even with E.G.O skills banned
【4. Mirror Dungeon Team Building: New Ideas for Tremor-Sinking Teams】
If you do not want to rely only on solo clears and prefer using a normal team for high-difficulty content, the new E.G.O from this Walpurgis Night also opens up new directions for Mirror Dungeon team building.
Based on practical testing, the team-building logic for Tremor-Sinking teams is as follows:
Core members (six-person formation):
Slot 1 choice: Before Floor 10, use “Zanshu” for stability; after Floor 11, switch to “Zunaxiang” for higher damage
Tremor Identities: Choose from Meursault (Moeheng), Lorenzina, and Sinclair (Eomsing) based on your roster. If you have Harmony E.G.O, prioritize Sinclair
Gregor slot: Choose either Ramgreg or Edgargreg
Bench Identities: Prioritize meeting the 5 Desperado condition first, then aim for 10 Muk Cloud if you have enough room
E.G.O Gift Route:
Starting observation: Recommended picks are “Prestige Card,” “Ginger Flower Branch,” and “Frozen Howl”
Floor 1: Factory Automation; farm “Possessed Shoes” + “Tailored Suit”
Floor 3: Bullet Point; farm “Serrated Fragment” + “Melee Tactical Manual” + “Black Flame Tube”
Floor 4: Hatred and Despair; obtain at least five or more Lobotomy E.G.O Gifts to prepare for the coffee cup event in the later “Amber Dusk Ordeal”
Floors 5-10: For fixed packs, prioritize “Sinking Gloom/Sinking Surge” and “Unchanging” to obtain “Black Cloud” and “Broken Glasses”; then take “Amber Dusk Ordeal” and “Time Killing Time Rerun” to assemble core Gifts
Floors 11-13: Take “Bloody Stench” and “Fairy Tale” to strengthen ammo and Tremor Gifts
【5. Walpurgis Night Identity Priority: What Should Veterans Pick?】
Based on community consensus, the recommended strength priority for this Walpurgis Night is: Solemn Lament Yi Sang E.G.O > Dawn Office Faust > Dawn Office Gregor > Dawn Office Sinclair.
However, if you are aiming for system completeness and want to assemble the full Dawn Office trio, the suggested order changes slightly: get Dawn Office Faust first as the Tremor team core, then add Dawn Office Gregor as a strong damage dealer, and leave Dawn Office Sinclair for last since he relies on the first two to reach full strength.
Final Summary:
The biggest value of this Walpurgis Night is not simply in pulling new units, but in the complete rewrite of Tremor team construction. Dawn Office Faust pushes out Mao Faust, and Solemn Lament Yi Sang allows Tremor and Sinking to coexist — these are not just cases of “number inflation,” but a reshuffling at the system level. The event ends on July 23. Whether you plan to pull or cheese your way through, the first thing to do is prepare your Ring Yi Sang.
