The Artifact Equipment in Final Fantasy XIV is obtained through a combination of questing and treasure hunting. The Artifacts for any given job are obtained toward the end of the line of quests involved in unlocking that job and its abilities. A player cannot initiate the quest specific to seeking Artifacts until they have reached at least level 45. Most Artifact pieces have stats comparable to that of single / double melded gear and unique, job skill enhancing effects such as reducing a certain ability's cooldown or increasing it's damage that are unique to them and cannot be found in any other piece of equipment or materia in the game.
The leg equipment for each job is invariably found in either Dzemael Darkhold, Cutter's Cry, or Aurum Vale. Two other gear pieces are always in certain chests all around the world that can usually be reached solo, and the fourth piece is inside one of the beastman strongholds.
The body equipment is earned alongside the job's 15-minute ability at the end of the quest line after an intense battle that often takes a full party to complete.
Other than the armor, there's also unique weapons that can be obtained from a separate quest.
Unlike Final Fantasy XI, not all artifact pieces can be obtained on one's own.
so in the benchmark program, the artifact armor is what a paladin would look like on a full set then, about the benchmark, can i change the different artifact armors instead of just the paladin? been messing around with it for awhile and don't see a way to change it up
