You can use the Rusted Key in Diablo 4 to open a locked door at the Belfry Zakara dungeon and complete one of the objectives. The Rusted key drops from an elite enemy named Anchorbound Chaplain and completes one of the objectives of Belfry Zakara.

  • But before slaying the Anchorbound Chaplain enemy, you must destroy two Drowned Bells and travel to Salt Scarred Marbles to make him spawn.
  • Then, you can find a skull indicating the Anchorbound Chaplain on the mini-map. Now, all that remains is finding the elite enemy throughout the dungeon.
  • After finding and defeating the Chaplain, loot the Rusted Key from the elite enemy.
  • Finally, use the Rusted key to open the locked door in the dungeon and complete another objective.
  • Once you unlock the door and head inside, you must defeat the Drowned Seahag boss in D4 for beating the dungeon.

For more clarity, here are all the objectives of the Belfry Zakara dungeon in Diablo 4:

  • Destroy two Drowned Bells and travel to Salt Scarred Marbles.
  • Defeat the Anchorbound Chaplain and collect the Rusted Key.
  • Use the Rusted Key to open the Locked door.
  • Defeat the Drowned Seahag boss.

Upon beating this boss, you will receive a Legendary aspect named Aspect of the Ursine Horror as a reward. This legendary aspect is an offensive enhancement for Druid classes that deal with tectonic spikes after casting Pulverize for two seconds.
