Limbus Company Sinking Team Build: Rime Shank Deluge

Sinking stands as the undisputed sovereign of status archetypes in high-level Limbus Company encounters. Operating with dual utility, Sinking completely dismantles human boss encounters by driving their Sanity down to -45 SP, while simultaneously dealing thousands of points of unblockable Gloom damage against colossal Abnormality targets.

The pinnacle of Sinking optimization revolves around the Sinking Deluge mechanic, which converts accumulated Potency and Count into a concentrated single-hit explosion capable of skipping entire boss fight phases.

Core Mechanics: Potency, Count, and Sinking Deluge

To operate a Sinking team effectively, you must understand the mathematical interplay between its two numerical values:

Target Sinking Debuff: [Potency / Count]
Example: [30 Potency / 6 Count]
- Every hit on target deals 30 Gloom damage (or -30 Sanity).
- Each hit reduces Count by 1: [30 / 6] --> [30 / 5] --> [30 / 4].
- If Count hits 0, the entire 30 Potency stack is wiped out.

The Sinking Deluge Nuke Formula

Introduced on Spicebush Yi Sang’s Skill 3 (Sinking Deluge), this mechanic multiplies current Sinking Potency by current Sinking Count, deals the entire sum as instant Gloom damage, and resets both values to zero.

$$\text{Deluge Damage} = \text{Sinking Potency} \times \text{Sinking Count}$$

A target stacked to 50 Potency and 12 Count sustains 600 base Gloom damage from Deluge alone, before factoring in Gloom resistance multipliers, stagger damage amplifiers, and critical strikes. With stacked damage amplifiers, Deluge hits deliver devastating burst damage in a single action slot.

Premier Roster Blueprint: The Sinking Hexad

The ideal six-person active frontline balances raw Count application, tanking resilience, and burst execution:

Slot Position	Recommended Identity	Operational Role	Key Synergy Contribution
Slot 1 (Anchor)	Wild Hunt Heathcliff	Primary Clash & Burst	Dullahan Mount AOE & Coffin mechanics
Slot 2	Dieci Association Rodion	Tank & Sinking Engine	Rime Shank E.G.O & discard shielding
Slot 3	Spicebush Yi Sang	Deluge Finisher	Skill 3 Sinking Deluge burst detonation
Slot 4	Dieci Association Hong Lu	Blunt DPS & Clash	High base power & discard cycling
Slot 5	Edgar Family Butler Outis	Debuff & SP Battery	Sinking Echo & party sanity restoration
Slot 6	Edgar Family Heir Gregor	Gloom Fragility & Count	Gloom resistance debuffs & resonance

1. Wild Hunt Heathcliff (Primary Damage Carry)

Wild Hunt Heathcliff fundamentally redefined Sinking strategies upon release. His mechanics grant him bonus clash power based on enemy Sinking stacks.

• Skill 1 (Phantom Tether): Generates Envy and applies Sinking count on clash win.
• Skill 2 (Dullahan Rampage): Multi-coin blunt assault that deals massive stagger damage when target has high Sinking potency.
• Dullahan Mount State: Consumes Coffin stacks to mount his steed, transforming all skills into high-ceiling AoE strikes that preserve Sinking Count.

2. Dieci Association Rodion (The Rime Shank Engine)

Dieci Rodion functions as the defensive anchor and the primary catalyst for Sinking acceleration. Her Discard mechanic filters low-tier skills to generate thick protective shields, allowing her to redirect dangerous boss attacks without taking damage.

Crucially, Rodion equips the TETH E.G.O: Rime Shank. When awakened or corroded at Threadspinning Tier 4, Rime Shank applies an astonishing +8 Sinking Potency and +6 Sinking Count to three enemy targets. This single skill instantly solves the archetype’s Count depletion problem for subsequent turns.

3. Spicebush Yi Sang (The Deluge Detonator)

While his basic skills provide modest Sinking contribution, Spicebush Yi Sang is brought specifically for Skill 3.

• Turn 1 to 3: Use Skill 1 and Skill 2 to cycle Gloom and Gluttony sins while other squad members stack Sinking.
• The Detonation Turn: Once the target reaches 40+ Potency and 8+ Count, fire Skill 3 into the staggered part. The Deluge check triggers on the final coin, deleting the boss health pool.

4. Dieci Association Hong Lu & Butler Outis

Dieci Hong Lu provides immense blunt clash power and discards his Skill 1 to cycle high-coin Skill 2 and Skill 3 strikes. Meanwhile, Butler Outis introduces the Sinking Echo effect, causing targets to lose additional Sanity and take bonus Gloom damage whenever an ally lands an attack.

Tactical Turn Pacing & Resource Rotation

Operating the Sinking team follows a precise three-phase combat rhythm:

Phase 1 (Turns 1-2): Setup & Resource Stockpiling
- Prioritize Gloom and Envy generation.
- Clash with Dieci Rodion and Wild Hunt Heathcliff to establish early stacks.
- Reach +45 Sanity across all six combatants.

Phase 2 (Turns 3-4): The Rime Shank Supercharge
- Target is staggered or entering a high-threat phase.
- Rodion unleashes Threadspinning 4 Rime Shank (Gloom 5, Envy 1).
- Target Sinking surges to 40+ Potency and 10+ Count.

Phase 3 (Turn 5): Sinking Deluge Execution
- Spicebush Yi Sang fires Skill 3 into the primary target.
- Target sustains thousands of burst Gloom damage, bypassing phase mechanics.

E.G.O Loadout Priorities

Equip these critical E.G.O to support your squad:

1. Rime Shank (Rodion - TETH): Absolute mandatory priority; requires Threadspinning 4.
2. Fluid Sac (Faust - HE): Sustains team SP and health; fueled easily by team’s high Gloom production.
3. Sunshower (Yi Sang - WAW): Provides massive AoE Gloom damage and inflicts Sloth fragility for mixed vulnerability phases.
4. Binds (Heathcliff - WAW): Immense crowd control tool that inflicts paralyze and heavy Tremor to lock down opposing bosses.

Mirror Dungeon Optimization

In Mirror Dungeon runs, Sinking teams achieve near-instant clears by targeting specific E.G.O Gifts:

• Midwinter Nightmare (Tier 4 Fusion): Created by fusing Rime Shank-adjacent gifts. Causes all Sinking applications to double their Count, turning every attack into a net-positive Count generator.
• Headless Fish: Inflicts Sinking Count at combat start, ensuring targets never drop to 0 Count on Turn 1.
• Thorny Path: Punishes enemy attacks with automatic Sinking infliction on clash loss.
