Rerun and refarm the limited time access dungeons.
There are named spawns inside that you might love to kill them over and over for their loot. However, you will have to waste a lot of time to complete all levels and come back to kill them again. After all that, maps will be regenerated and you will have to locate them over again. It is possible at current game state to save your time and skip all those hassles.
All you have to do is locate theses bosses either by grinding your way through or die and locate them as a ghost.
Now kill all of them and collect your loot.
Then simply log out inside. The random generated area will be restocked and you will be able to farm the same spawn on the same map over and over.
