Understanding the Vault of Copper

The Vault is a new dungeon where you will navigate hazards, and traps, and face hordes of Constructs to uncover treasures. There are four types of Vaults, accessible through the Gatehall, a new Hub situated in Kehjistan.

Traversing the Vault

  • Breaking down the four main areas of the Vault and their trap mechanics.
  • First area: The upside-down T-shaped room with spike traps and electrified darts.
  • Second area: Navigating the electrified panel hallway with caution.
  • Third area: Collecting the Keystone amidst electrified panels and rotating pillars.
  • Fourth area: Managing traps and Dart pillars for safe passage.

Tips and Strategies

  • Suggested number of Warding Charges to ensure access to all chests.
  • Importance of acquiring Unstoppable skills to counter-control impairing effects.
  • Dealing with the challenging Son of Malphas Boss encounter.
  • Staying vigilant against trap-filled doorways.

Rewards of the Vault

Completing the Vault with no Warding stacks left rewards you with minor chests containing Legendary D4 items for sale, a guaranteed Tuning Stone, and other small rewards. If you finish with at least one Warding stack, you can open the Wardwoven Chest, offering Governing and Tuning stones, more Legendary items, and a chance at rarer loot.

Furthermore, defeating the Vault’s final encounter will also drop a chest with a guaranteed legendary item from level 26 onwards. Additionally, these chests have a 35% chance of dropping another legendary. We recommend aiming to finish with as many Warding stacks as possible for better loot at the end of your vault run.


Mastering the Vault of Copper in Diablo 4 Season 3 is a rewarding and exhilarating experience. With careful planning, lightning resistance, and a keen eye for traps, players can emerge victorious and claim the bountiful rewards that await them.
