Understand the core currencies of Arknights: LMD (Luminous Metal), Orundum, and Originium Prime. Learn how to acquire and best utilize them for Operator recruitment and progression.

Arknights features several key currencies essential for player progression. These include LMD (Luminous Metal), Orundum, and Originium Prime. Each currency serves a distinct purpose in acquiring new Operators, upgrading existing ones, and progressing through the game's content.

• LMD (Luminous Metal): The most common in-game currency, primarily used for Operator promotions, skill upgrades, and base facility construction/upgrades. It is earned through various game modes, including stages, missions, and base production.
• Orundum: A premium currency primarily used for Headhunting (gacha pulls) to obtain new Operators. It can be acquired through daily missions, event rewards, and by converting Originium.
• Originium Prime: The rarest premium currency. It can be purchased with real money or obtained through specific achievements and first-time stage clears. Originium Prime can be converted into Orundum, used to purchase Headhunting packs, or used to refill Sanity (stamina).
