Boss and dungeon loot
Farm boss dungeons after resetting zones
Reuse campaign or endgame boss routes for another chance at enemy and chest loot after the area instance resets.
A campaign or endgame boss dungeon that your character has already unlocked.
Repeat when the dungeon instance has reset. Boss drops and chest contents are random; the route does not guarantee a specific item.
Switch to another dungeon or Mapworks run if the boss instance remains unchanged or repeated clears no longer produce useful upgrades.
Open a guide to find other locations and see what the item is used for.
