Episode Pass on Webstore?

Don’t know about the web store, but In the game you can go to Quests -> Episodes screen. 

There's an Activate button in the upper right next to the locked episode graphic. It brings up the purchase screen.

Hope that helps …

I'm guessing the OP is asking about the webstore because you get the webstore currency (forget what it's called) when you make purchases there.  You can buy the Conquest pass on the webstore so I would think you could get the episode pass as well.  It's not showing up right now, maybe check after the next reset?

am I missing something from your question or was it added sometime in the last few min?
