Diablo 4 Season 3 – What Is the Seneschal Companion? Mechanical Friends Explained

There is a new type of companion coming with Season 3. Read on to find out what is the Seneschal Companion in Diablo 4 Season 3.

Diablo is a popular ARPG made by Blizzard Entertainment. The core of the game is fighting demonic hordes using weapons, abilities, and magic. Moreover, you can also have a companion by your side, to help you out. Usually, you get the pick of the type of companion you bring along. If you are on the more squishy side, you may want a beefy companion to tank the hits. Or if you are a more direct fighter, having some ranged support is quite handy. In Season 3, there is a new type of companion, exclusive to that Season. Read on to see what is the Seneschal Companion in Diablo 4 Season 3.

What Is the Seneschal Companion in Diablo 4 Season 3?

Seneschal Companion is a new feature coming with the Season of the Construct. It is a mechanical construct that you can modify and upgrade to your liking. It becomes available during the Seasonal questline and Zoltun Kulle designed them to help you out on your adventures by “engaging directly in the fight or aiding you dutifully on the sidelines.”

As mentioned earlier, Seneschal Companions can be modified to serve a certain purpose. You can do so by finding special Stones – Governing Stones and Tuning Stones. 

What Seneschal Companion Does in Diablo 4 Season 3?

Seneschal Companions can be modified by finding and using Governing Stones and Tuning Stones. These can completely change the way you Seneschal behaves. Your Seneschal can be a ranged powerhouse, optimized for close combat, or there to buff and shield you. Governing Stones determine the main abilities your companion has. You can have up to two Governing Stones/abilities active at the same time. The other type, the Tuning Stones, is there to amplify the chosen abilities, and you can have three Tuning Stones active per Governing Stone. In total, you can have two Governing Stones, each with three Tuning stones (six in total). Think of Governing Stones as Skills and Tuning Stones as Passive Skills, just for your little mechanical friend.

You can find these Stones by completing Vaults, a new type of dungeon, coming with Season 3. Moreover, you can craft Governing and Tuning Stones by collecting some Shattered Stone, a crafting material you get by defeating Constructs in Vaults.

Lastly, Stones can be upgraded by fusing together duplicates of the same one, for increased potency and improved abilities.

Governing Stones

• Autodefense: The Seneschal Construct activates an antimaterial field around itself shooting down enemy projectiles. Can not shoot down Boss or Player projectiles.
