A Merit is a form of currency that can be earned by completing Daily Missions or participating in Events. Merits can be used to buy items from Faction Centers, which include Faction Transmissions. They will also be used to bring crew out of the Vault.
Merits are one of several currencies in Star Trek Timelines, such as Credits and Dilithium. Merits cannot be bought directly using dilithium. Players can check how many merits they have at the top of the screen in specific areas such as the Daily Missions or within a Faction Center.
