The Limbus page has been spiffed up for the Limbus renewal, including pages for each of the four new Limbus areas. Maps and information for the first tier battles have already been added based on test server results and just need verification that they were not changed prior to implementation in the actual game. The second tier battles (Arch-Omega and Arch-Ultima) will need more information, although there was some info on Arch-Omega prior to it being added. The precise method of obtaining the new armor sets also needs to be added once discovered, although it is likely that it simply involves trading new Arch-Omega/Arch-Ultima components with or without old Homam/Nashira components.

The only new element of Einherjar is Odin's Chamber II, whose page is basically unpopulated, but should be updated rather quickly as people clear the battle. Relevant access information with the Mark KI, etc., has been added/updated on the main Einherjar page.

The Voidwatch Weaknesses page has been adjusted significantly to reflect the changes to the weakness list. Minor changes to the Voidwatch main page have also been added, including a brief synopsis of Pulse Panoplia and Pulse Cells.
