Relics are very powerful artifacts and trophies that an empire can collect if they defeat a crisis or own the required DLC. Every Relic has a passive effect as well as a powerful Triumph effect that requires resources. All Relics have a Triumph cooldown during which no other relic can be activated. Relics have a cooldown of 10 years.
Relics give large amounts of score, which can tip the balance in games with victory enabled. The Relics Collected score for empires in the victory tab can be used to deduce which empire has relics.
