Since the new season, the seasonal quest has problems, it doesnt show on map, dont get updates. Have to join partys to collect. And after that you have to kill bilail, nice afterwards i want to kill it again, but cant open chest eventhough i have enough materials
There are no seasonal quests in Diablo Immortal.
Belial doesn’t feature in Diablo Immortal
I suspect you’re lost…
A Google search for diablo iv forums gives this as the first returned link…
There are lots of Bug Report threads about Belial…
