Eureka Armor Sets are level 70 relic Armor sets. Players can obtain the first set of Eureka Armor after clearing the level 70 job quest and gaining access to The Forbidden Land, Eureka Anemos. Unlike the Eureka Weapons some Eureka Armor Sets are acquired individually without having to complete previous steps of Eureka Armor.
Antiquated Armor Sets (ilvl 290) are acquired by completing the Stormblood job quest line for your given job, up through the level 70 quest. If you misplaced or discarded your Antiquated Armor Sets, you can purchase a replacement for 1,000 Gils from the Calamity Salvager in any of the three starting cities.
