Limbus Company's premium currency, Lunacy, fuels the acquisition of new Identities and EGOs—the game's core gacha system. Securing ample Lunacy is crucial for expanding your roster of character variants.
Lunacy acquisition mirrors most gacha games: plentiful initially, then tapering off with progression.
How to Acquire Lunacy:

Early-game players should prioritize the main story. Each chapter yields approximately 390 Lunacy, with an additional 260 for achieving sufficient EX-rated mission completions. First-time EX clears grant an extra 40 Lunacy. First-time Luxcavation stage completions also provide Lunacy, but these are one-off rewards.
Post-story completion, Lunacy acquisition slows. Focus on these methods:
- Boosted Mirror Dungeons: The most consistent source. Three attempts weekly (resetting Wednesdays) yield 750 Lunacy. These are challenging, requiring your strongest Identities.
- Events: Time-limited events offer substantial Lunacy. Maximize participation for optimal gains. Thoroughly review all event rewards.
- Uptying Identities: Upgrading Sinners' Identities and EGOs to Uptie Tier 3 awards 40 Lunacy per Identity. While finite, this is a long-term strategy. Consistent character leveling and Thread acquisition are key.
- Battle Pass Rewards: Offers various resources, including Lunacy. A free track exists, but purchasing the premium pass unlocks all rewards.
- Direct Purchases: The most direct, albeit costly, method.

Strategic utilization of these methods ensures a steady supply of Lunacy for continued roster expansion in Limbus Company.
