I visited Grandmaster Hobbs to purchase the recipe for Exitus - it is not available for me to buy. I have completed only one Legendary - I started the journey for the Bifrost and completed the first level - a friend gave me the precursor so I didn't have to go through the rest of the crafting for the pre to make the legendary. I've got the journeys to Twighlight and Dusk started.
There doesn't seem to be a Pharus journey available to start. Is there a pre-requisite I might be missing? I've completed the All or Nothing Story, haven't completed all the achievements.
