With the new Alpha build going up today, we're going to enable some initial testing of one piece of Azerite Armor, with one set of choices. To access it, you'll need to create a new character, and you'll find it equipped on your character.

Note that some elements are still placeholder (including the UI), but we're still interested in any early feedback you have on this feature. We'll be rolling out additional pieces of Azerite Armor for testing as the Alpha continues.
