Along with all of the new content and quests to explore (including new Hildibrand quests), players will be able to queue up for leveling roulettes as a party and obtain music rolls for the new Orchestrion furnishing from a variety of sources. Several tank abilities have been adjusted, with tank damage calculation now based upon VIT rather than STR. There’s also a list of new armor to be crafted or found, dyeable Allagan gear replicas from the Binding Coil, and new items to be obtained from the Void Ark. Check out the full patch notes, or just take a quick gander at the patch trailer just below.
