Diablo 4 Season 3 New Boss Battle: Keeper of the Vaults

New Boss Battle: Malphas, Keeper of the Vaults

The Demon uses both this possessed Construct Guardian and the arena itself to attack players.

Malphas will harness the power of the Elements, attacking with powers of Cold, Fire, Lightning, Poison.

First stationary boss in Diablo 4 - will not move around arena, but the boss will weaponize the arena against you.

Elemental Pillars will stand around the boss battle arena:

One pillar per each Elemental type.
When players attack and disable a pillar for a limited time, boss is forced to switch to a new Elemental type, preventing the boss's attacks from getting too strong.
Paired with elemental resistances, these pillars can help tip the fight in the player's favor.

The Level of difficulty is comparable to Varshan*.

Malphas, Keeper of the Vaults can be challenged again in the Echo of the Keeper instance same as previously with the Echo of Varshan.

Echo of the Keeper will drop better loot in WT4 but the difficulty increases.

The Echo of the Keeper instance is available in WT1, WT2, WT3 and WT4.

New Seasonal Dungeons: Vaults

Teeming with unnatural Constructs and deadly Hazards, Vaults were created for protection but are now harnessed by The Demon.

Ayuzhan and Zoltun Kulle crafted Hazards and Constructs to protect and maintain the Loom, powered by elemental magic.

Now, the Demon has taken control of the Hazards and Constructs, putting them to work for his devious plot.

Diablo 4: Season 3 - Inside the Vaults Dungeon — **Diablo 4: Season 3 - Seasonal Dungeons**

The Vaults

There is one Vault per Element that players can access.

The Vaults are filled with Hazards.

traps that various triggered damage types such as Elemental Grates, Elemental Darts, Exploding Chests.

in The Vaults you fight the new Construct monster types:

Courtier Construct - (spider) skittering creation rushes its target, overwhelming them.
Vizier Construct - (wasp) hovering creation keeps distance from target, attacking with projectiles that match the element type.
Guardsman Construct - (scorpion) burly creation that steadily closes in on its target.

Vault mechanics

When players enter Vaults, they get Zoltun's Ward, a buff that shields them from on hit of a Vault Hazards but goes away when hit.

If players manage to keep Zoltun's Ward until the end of the dungeon, they will be able to open a Wardwoven Chest.

Players can play the new Dungeon: Vaults at any time to earn rewards:

Boss drops the default Vault reward.
Wardwoven Chest can only be opened if player still has Zoltun's Ward*.
Nightmare Vaults can be played from WT3 and above, Vault Sigils will drop or be craftable like Nightmare Sigils but requires Pearls of Warding*.

Your Seasonal companion: Seneschal Construct

Season 3 brings a new mechanic, the companion system in Diablo 4.

With Ayuzhan's help, the Wanderer revives an uncorrupted Seneschal Construct, and it becomes their Seasonal Companion.

The Seneschal Construct companion unlocks during the Seasonal Questline.

Using magical Stones recovered from Vaults, you can craft Companion abilities to augment their own combat skills and to enhance Vault exploration.

The Seneschal Construct is a highly customizable pet-like Seasonal Companion:

Once acquired, it follows the Character everywhere until Season 3 ends.
It uses its abilities independently of the Character but can create combo opportunities.
Its base stats scale with the Character.
It does not have health, so it cannot die but it will have a stagger though.

Companion Mechanics

The Seneschal has two attacks/skills.

Players upgrade the Seneschal's attacks by modifying Stones in its Cryptex:

Governing Stones dictate the attack type.
Tuning Stones. These augment the Governing Stones by adding additional mechanics such as shooting additional projectiles or changing the damage type entirely.

“Where to find Seneschal Stones?”

Governing stones can be acquired from season’s questline, Vaults, Wardwoven Chests, Season Journey, crafting with Shattered Stones at the Jeweler. (Defeating enemy Constructs within the Vaults will also grant Shattered Stones)

Tuning stones can be acquired from Season Journey, seasonal content, Vaults, crafting with Shattered Stones at the Jeweler.

You can equip your Seneschal with 2 Governing Stones and 6 Tuning Stones, one Governing stone for each attack and three Tuning Stones to augment the ability. There are 12 Governing Stones and 27 different Tuning Stones of different rarities to seek out in the Vaults to unlock the full power of the Seneschal construct.

“How to level up the Tuning and Governing Stones for the Seneschal Construct companion?”

To level up the Tuning and Governing Stones collect or craft duplicates of the same Stones and merge them together to increase the experience and eventually level up your base Stones.

Increasing the level of the stones increases the potency and ability of the attacks.

Increasing the level of the Tuning Stones can add additional projectiles or augment the damage type the have.

Building your Seasonal Companion

Building your Seasonal Companion use Governing & Tuning Stones to create the perfect Seneschal Construct.

Governing & Tuning Stones are variants of Paragon glyphs, they are not items:

Governing Stones do not have a Level or Rarity, only need to be acquired once.
Tuning Stones have Level and Rarity, and improve linearly with level.

The Seneschal's Cryptex appears as a Seasonal Inventory tab, similar to the Sanguine Circle in Season 2.

From this, players can easily swap Governing and Tuning Stones for their Companion.
