Final Fantasy XIV? A week ago? A month? Was it never? Well, perhaps you should drop back in, because there's some new stuff in there. New armors. Attractive armors. And don't worry that veterans will have them right away when you log in; these armors require climbing the PvP ranks further, as this patch also adds ranks 31-40 to the ladder. So there's that much more reason to jump into the arena and start earning your Wolf Marks.
Patch 2.25 also adds a couple of other features. Players can now use materia transmutation to exchange unwanted materia for a (hopefully more desirable) piece of materia at random. Darklight gear has been made dyeable, and Ventures have been added as a possible reward from treasure hunts. Take a look at the full notes for a few more details as well as a list of bug fixes included with the patch.
