Blizzard announced that an upcoming hotfix will resolve the issue of console players losing access to Vessel of Hatred! Players can also work around this issue by logging out and back in, or by swapping to a non-Spiritborn character once.
Vessel of Hatred Spiritborn Guides
The plan is for this to be in our next hotfix.
The workaround for now is to log out and back in or by swapping to a non Spiritborn character and then back again.
Apologies for this but we are hoping to have a fix out for this soon!.
