Limbus Company's premium currency, Lunacy, is crucial for acquiring new Identities and EGOs—the game's gacha system. Securing a plentiful supply is key to expanding your roster.

Lunacy acquisition mirrors other gacha games: abundant early on, tapering off with progression.

How to Obtain Lunacy:

Initially, the main story is your best source. Each chapter yields approximately 390 Lunacy, with an additional 260 for sufficient EX-rated mission completions. Achieving an EX rating for the first time on a mission grants an extra 40 Lunacy. First-time Luxcavation stage clears also provide Lunacy, but these are one-off rewards.

Once the main story is exhausted, these methods become paramount:

• Event Stages: Completing or achieving EX ratings in event stages offers consistent Lunacy. These are time-limited, so prioritize participation.
• Boosted Mirror Dungeons: This is arguably the most reliable method. Three attempts are available weekly (resetting Wednesdays), yielding 750 Lunacy. These dungeons are challenging, requiring your strongest Identities.
• Uptying Identities: Upgrading Sinners' Identities and EGOs to Uptie Tier 3 rewards 40 Lunacy per Identity. While finite, this is a long-term strategy, as reaching Uptie 3 requires significant investment.
• Battle Pass Rewards: The battle pass offers free and premium Lunacy rewards. The premium track requires a purchase.
• Direct Purchase: Lunacy can be directly purchased using real money.

In summary, while early game Lunacy acquisition is straightforward, maintaining a steady supply requires a multifaceted approach, combining event participation, consistent Mirror Dungeon runs, strategic Uptying, and potentially battle pass purchases.
