Every new season of Diablo 4 needs a common material that can be constantly collected, and in the Season of the Construct, that material is Shattered Stone. If you want to make your Seneschal companion as strong as possible, it’s time to start finding stones.
How to Farm Shattered Stone in Diablo 4 Season 3
The best way to get Shattered Stone is by killing construct enemies in Nightmare Vaults or Arcane Tremors during Season 3. Standard construct enemies will drop a low amount of the common stone material any time you kill them. If you want a higher concentration of the material, you should hunt down construct Elites, which will drop higher amounts of Shattered Stone at one time.
