Blizzard Entertainment's official World of Warcraft website is featuring a handful of articles on some of the additions being made in the game's forthcoming v4.3 patch for Cataclysm. Among them are a piece on transmogrification, a piece on void storage, a piece on the Darkmoon Faire, and a closer look at the new Gilneas faction mounts. A snip on transmogrifying, followed by a bit on void storage:
Placing an item into the Transmogrifier interface will offer a preview of how the item will appear once the change is applied. However, not all item pairings are compatible with Transmogrification. In general, only items that have stats can be used in the transmogrification process. You must also be able to wear both items when using this service. Ethereals don't have much in the way of ethics, but allowing someone to appear as if they're equipping unusable items crosses the line. Similarly, they won't allow you to change weapon or armor types. Sneaky death knights can't make that breastplate look like a cloth robe, and you can't make a one-handed axe look like a two-handed axe, or transform a sword's appearance into that of a mace. Guns, bows, and crossbows will be the exception to this rule. You will finally be able to retain your dwarf's racial gun bonus while appearing with all the splendor and elegance of a bow wielder (or at least the relative silence of one).
Placing items into the Transmogrify interface will increase the gold cost of the process, and clicking the Transmogrify button (assuming you have the necessary funds) will put the appearance change into effect. The process can be reversed by clicking the undo icon on each item, and then hitting the Transmogrify button once more to save the changes. Any item that's transmogrified will have text indicating it's been altered by the process for all to see, similar to the item tooltip callout for reforged items.
A variety of items can be placed into Void Storage -- including soulbound items and Battle.net Account Bound items -- making it the perfect location to store trophies from past conquests, as well as armor you may want to hold onto for Transmogrification. So, if you've been looking for a good home for those old tier sets or your vanity holiday items, Void Storage is it! And it's as easy to use as dragging and dropping.
In return for this unique service, the Ethereals will require a small fee for each item deposited into or withdrawn from their Void Storage apparatus. Multiple items can be added and removed at once, and the cost of each transaction will be display at the bottom of the screen, updating dynamically as you select additional items to deposit or withdraw. Once an item is placed into Void Storage, it can remain there indefinitely for no additional cost.
