Once you acquire the Ex Diris you will get the Catalyst quest from Banshee in the Tower. In order to complete the quest to obtain the catalyst, you must complete a lengthy set of objectives in both PVE and PVP playlists, but it's well worth it once the catalyst is finished!
Please note: YOU MUST HAVE ALREADY REACHED LEVEL 22 IN YOUR SEASON PASS. IF YOU HAVE NOT, we will either help you level to 22 for an additional price or delay your order until it has been reached.
