After a long wait, patch notes for Patch 1.20 have been released, and the amount of content this patch rivals that of patch 1.19. By content, we mean the sheer volume of information. In terms of brand new content, we can only expect the new Moogle Primal battle, Good King Moggle Mog XII. Besides that, there have been a number of tweaks to older content, including a mmethod to receive the Ifrit weapon of your choice, and various adjustments to Behest and Caravan Security Missions. You can also expect a number of new Grand Company leves and quests to be added. Still the biggest change is the Class Reform. The action and trait lists have been finalized and readily accessible to all players. You can choose whatever section floats your boat below, and see for yourself.
