Limbus Company: How to Solo Walpurgis Night Hard With Sinclair

To clear the Walpurgis Night [Hard] encounter solo with Sinclair in Limbus Company, enter the stage with Sinclair as your only deployed Sinner, survive the 0 Sanity opening turn, and use his expanding skill slots to control enemy clashes. Fielding Sinclair alone funnels the team's entire surplus action economy directly into him, allowing him to gain a new skill slot every turn until he hits the stage deployment cap. Because he takes every clash on the field, he can reach maximum +45 Sanity (SP) within two turns, locking his skill coins to a 95% Heads flip rate and dominating the encounter.

Recommended Identity Choices and Requirements

A solo run requires high base speed, consistent coin ceilings, and a reliable defensive skill to mitigate damage when clashing is unsafe.

• Cinq Association South Section 4 Sinclair: The most consistent duelist for this encounter. He gains Haste and Clash Power Up through his Declaration of Duel mechanic, and his Speed-scaling Evade defense skill can dodge multiple attacks in a single turn.
• Lobotomy E.G.O::Red Sheet Sinclair: A high-offense alternative that applies heavy Rupture and Talisman stacks to shred the boss. You must monitor his status effects closely, as stacking more than five self-inflicted Talismans causes Sinclair to take Rupture backfire damage.
• Dawn Office Fixer Sinclair: Delivers heavy Burn application and high clash power after triggering E.G.O Manifestation, but requires steady kill tempo and clash wins to offset his per-turn Sanity decay.

Fill every bench slot before starting the stage. Bench passives that trigger automatically without Sin Resonance—such as healing from Base Gregor or G Corp Manager Outis, and SP restoration from Base Hong Lu or Lobotomy E.G.O::Sloshing Ishmael—provide steady passive sustain while Sinclair fights alone.

How to Play the Opening Turns

The highest risk of failure occurs on Turn 1 when Sinclair has only one skill slot, no defensive safety net, and a baseline 0 SP that gives coins a 50/50 flip chance.

1. Check Turn 1 Matchups: Compare Sinclair's speed against the fastest incoming attacks. If you have the speed advantage to redirect an attack and the clash preview predicts "Favored" or "Dominating," take the clash to generate immediate SP.
2. Defend If Outmatched: If incoming attacks show "Neutral" or "Struggling," do not risk an offensive clash. Convert your single slot into an Evade skill. A successful Evade negates all incoming damage from the targeted strike and rolls again against any subsequent attacks aimed at that defense slot.
3. Stabilize on Turn 2: Sinclair gains his second skill slot on Turn 2. Direct one slot to clash against a low-rolling enemy attack to hit +45 SP, and use the second slot to deal unopposed damage or stagger an enemy add with Skill 2.

Clash Redirection and Target Priority

Once Sinclair reaches three or more skill slots, your focus shifts to managing enemy waves and neutralizing lethal boss actions through speed-based redirection:

• Area-of-Effect (AoE) and High-Threat Skills: When a boss targets multiple slots with an AoE attack or inflicts severe debuffs like Fragile or Paralysis, redirect it into Sinclair's highest-rolling skill (such as Cinq Sinclair's Skill 3, Fleche) or an E.G.O. Winning that single clash neutralizes the entire attack across all targeted slots.
• Multi-Hit Single Targets: Do not spend offensive skills trying to clash every high-damage single strike. Assign an Evade to your fastest slot targeting the enemy's fastest attack to dodge the barrage, leaving your remaining slots free to strike unopposed.
• Minion Elimination: Stagger and eliminate secondary adds before focusing the boss down. Minions deal chip damage that drains your health pool and risks pushing Sinclair past his Stagger threshold.

E.G.O Selection and Failure Points

Solo play relies on Sinclair's own skill deck to fuel his Sin resource bank. Monitor your Sin stocks so you can trigger key E.G.O skills when offensive rolls are insufficient:

• Branch of Knowledge (ZAYIN): A cheap clash override to salvage bad skill hands in the opening turns.
• Impending Day (TETH): A high-rolling Blunt attack that wins difficult mid-tier clashes and provides Sin resources and damage buffs upon scoring a kill.
• 9:2 or Lantern (HE): Essential high-tier clash skills that restore Sinclair's health pool if chip damage approaches his Stagger threshold.

A single misstep can end a solo run immediately. Restart the stage if Turn 1 flips Tails and inflicts heavy damage before you build SP. Watch Sinclair's Stagger bar closely; unlike in team play, being staggered skips your entire turn, strips your defenses, and leaves you unable to clash or evade incoming attacks. Finally, avoid attacks that inflict Sinking or direct SP damage, as dropping below +20 SP severely undermines coin consistency.
