With Patch 5.25 now available in Final Fantasy XIV, you can get a new set of class armors. These Idealized Armors are an upgrade of the already existing class sets that you obtain when finishing the main story of your job after level 80.
In order to get to drop these new shiny armors, you will first need to complete the instanced duty linked to the new Relic Weapons to unlock the Gangos Zone.
Once there you will simply need to talk to the Wandering Dramaturge (X: 6.8 Y: 5.2) and accept the quest to unlock the Trial.
This new Memoria Misera Extreme Trial unlocked you will need to fight Varis Zos Galvus to drop the new High Legatus Idol. The complete set needs 19 idols so make sure to speak with C’intana in Revenant’sToll to check which piece you want first.
NOTE: Only the new (ilvl 485) set is dyeable. If you only want it for the glamour and want to keep the original colors you can choose to go back to Grenoldt in TheTempest where you will be able to claim the ilvl 430 version of it for free!
