There are actually two new features that are making their way into the game with Patch 2.5, starting with the armory. The armory allows players to save up to five builds per character, taking a snapshot of their equipped build and then pulling that gear out of storage when needed. This way, characters can swap between gear load-outs much more easily than before.
The other feature is an additional storage tab devoted solely to holding a player’s crafting materials. “Crafting materials picked up or obtained through salvaging will now appear in a separate storage tab, freeing up space in the shared stash,” Blizzard said. “This tab can be accessed through the inventory window.”
