We have custom made so called "Relics", each Class has Access to a regular Relic (2.000 Rebirth Coins) with a required Level of 130 and its advanced Version (10.000 Rebirth Coins) with a required Level of 200. Advanced Relics provide higher Stats than the regular ones. Those Relics can be bought from the Rebirth Chest in North-Flaris. The Relics can't be upgraded.
