Lunar Coin

Lunar Coins are a special account-wide currency available in Risk of Rain 2, rarely dropped by enemies. They appear as giant silver coins with a blue outline and must be picked up manually via the Use key, after which they are tracked beneath your Gold with a purple $ sign. Unlike Gold, Lunar Coins acquired persist between levels, deaths, and even entire runs, allowing you to slowly accumulate more and later cash them in for powerful bonuses - especially if you have a particular build in mind.

They can either be redeemed at Newt Shrines to gain access to a special shop level, or used to open Lunar Pods in regular levels. In both cases, they can be used to acquire unique Lunar items which grant powerful bonuses, but unlike regular items also incur significant penalties or other unusual drawbacks. Lunar Pods grant a random Lunar item for a single coin, whilst specific items may be purchased (usually for a higher number of coins) in the shop level itself.

A total of eleven1 Lunar Coins are required to unlock the Artificer; one to gain access to the shop level, and another ten for the purchase.

1 - Since the Bazaar portal also has a chance to spawn in randomly, a minimum of 10 lunar coins is required to unlock the Artificer.
