Artificer Subclass

Is Artificer no longer an individual subclass that can be purchased? I've looked all over the site, enabled Eberron content, and I can't find it anywhere. 

Artificer isn't a subclass, it is a class. You can see Alchemist and Artillerist (subclasses of Artificer) are there on your list.

There's also Armorer as well as Battle Smith, which rounds out the set of 4 subclasses.

Purchase any one Artificer subclass and it’ll unlock the base class for you.

Thanks everyone!
