DC Universe Online, and you have a lot of different options available to you. You have a setup you like to use for dealing damage, a setup for healing teammates, even a setup for when you absolutely need to get across an entire zone in less than three minutes. Swapping between those is a bit more taxing, though. Wouldn't it be nice if you could just instantly swap between a full loadout and appearance with just one click?
Yes, that's exactly what Armories do: they allowing players to save an alternate build that can be accessed out of combat instantly. A free armory slot is given to every character following a quest, with additional slots (for additional builds) available in the marketplace for $6 (or less if bought in bulk). Each player base can hold four slots for a grand total of 16 Armory slots, giving you plenty of space to store all the alternate builds you could ever want.
