Diablo 4: Onyx Hold Dungeon

During my journey in Diablo 4, I witnessed that exploring Dungeons is the most popular activity in Diablo 4. It is the optimal location for farming a significant amount of XP. However, scouting the Onyx Hold Dungeon requires guidance, as you will be requested to complete objectives and eliminate the final boss. 

Key Takeaways

  • Onyx Hold is a Dungeon in Diablo 4 that operates as a Regular and Nightmare Dungeon.
  • The Dungeon is in the Dry Steppes region, close to the Waypoint.
  • Onyx Hold has several objectives, like slaying all enemies and eliminating Languishing Corpses that provide XP points when you complete them.
  • The dungeon exploration is completed after the objectives. However, there is also an optional boss called Arminel Flarebang, which you can defeat for Legendary loot.

A summary table includes everything you need to know about the Onyx Hold Dungeon.

Dungeon Name Onyx Hold
Type Optional
Pre-requisites Complete Onyx Watchtower Stronghold
Dungeon Location To the west of Onyx Watchtower Stronghold
Rewards Storm Swell Offensive Legendary Aspect, 30 Renown, Waypoint, Blacksmithing station access, Legendary Gear

Players can run Onyx Hold as a Nightmare Dungeon, allowing them to farm more XP for leveling up and collecting Legendary loot. However, you must complete the Onyx Watchtower Stronghold located in Dry Steppes. Make your way to this area from either Ked Bardu or Barbarian Town.

When I was on my way to complete the Stronghold, I found it useful to eliminate Bandits that spawn in the targeted location. Moreover, the family of Bandits will eventually take you to their captain. This is where I noticed that you must defeat him to open the Watchtower to act as a safe region.

  • After getting hold of the Onyx Watchtower, search around a similar region to find the Onyx Hold Dungeon.
  • Start your journey from the Waypoint.
  • Keep walking in the West direction until you stumble upon stairs going down to a hidden area.
  • If you still do not have the Watchtower access, you can travel from Fate’s Retreat, but it will consume more time without having a fast mount, such as a Horse.
  • Moreover, Sorcerers are expected to find the Storm Swell Offensive Aspect in this location, which is important for their builds.

Dungeon Objectives:

  • Slay all enemies in the area,
  • Eliminate Languishing Corpses,
  • Defeat optional Boss Arminel Flarebang.

When I got to the second half of the Onyx Hold, I saw Languishing Corpses discreetly placed around the Dungeon. Hence, I suggest you to eliminate all of them to complete the dungeon exploration. Although this is not compulsory, you can also engage in combat with an optional Boss, Arminel Flarebang.

The Onyx Hold Dungeons is marked as complete without defeating the boss. However, Flarebang will drop legendary loot if you take on him and emerge victorious.

You will receive the following rewards upon completing your exploration:

  • Storm Swell Offensive Legendary Aspect,
  • 30 Renown Points,
  • Waypoint and Blacksmithing station access,
  • Legendary Gear.

Worth It?

I learned from experience that exploring optional Dungeons like Onyx Hold is essential to Diablo 4. They let you test your gear and abilities through exploration and allow you to participate in combat. However, I must advise you to keep upgraded weapons and armor before exploring, as they protect you from the enemies more efficiently.
