Diablo 4 Season of the Malignant adds powerful new Malignant Hearts to the game. These items come with their own Legendary powers that can completely change your build. In order to get them, there are several new systems you’ll need to interact with, including Malignant Tunnels, Invokers, and Heart crafting.
Unfortunately, the game doesn’t explain Invokers too well, and you might be confused in the early hours of the season — especially if you didn’t tune into Blizzard’s recent announcement livestreams. But that’s where we come in.
In this Diablo 4 guide, we’ll teach you how to use Invokers, how to find them, and how to craft with Ichor in Season of the Malignant.
What are Invokers and how do you get them?
Invokers are consumables in Diablo 4 season 1, and you can use them in the new Malignant Tunnel activities — several of which are scattered around Sanctuary, and are denoted with a normal dungeon icon adorned with a green leaf on the world map.
Once you finish a Malignant Tunnel and “Dungeon Complete” flashes across your screen, a passageway in the Tunnel will open up. If you follow this new path, you’ll find a room with a Malignant growth event in the center, surrounded by two colored Outgrowths — a Wrathful “Super” Outgrowth and one of the other three Outgrowths: Brutal, Devious, or Vicious.
If you stab a Brutal, Devious, or Vicious Invoker into its corresponding Outgrowth, it will summon a giant monster. Killing that monster will net you a Malignant Heart that corresponds to the Invoker you used. This is a way to partially guarantee yourself a Malignant Heart of a specific type without having to rely purely on crafting. There are also Wrathful Invokers, but they’re very rare, particularly in the game’s early levels.
You can find Invokers around the world, like in Malignant Tunnels, but you can also craft them at Cormond’s workbench in Kyovashad. To craft them, you’ll need quite a bit of Ichor, which is its own complex system in Season of the Malignant.
How do you find Ichor to craft Invokers and Malignant Hearts?
Ichor comes in three flavors, which match the three Malignant Heart types: Brutal, Devious, and Vicious.
You’ll need all three types to craft an Invoker — 50 Ichor that matches the type of Invoker it is, and 20 of the other two flavors. To craft Malignant Hearts, you’ll need 35 Ichor each of the colors you’re not trying to craft. So if you’re crafting a Brutal Caged Heart you’ll need 35 Devious Ichor and 35 Vicious Ichor.
You can collect Ichor in one of two ways. The first is to simply find it lying on the ground after killing monsters. It’s a common drop from any and all creatures inside Malignant Tunnels, so that’s a great place to start if you need to craft the Brutal Malignant Invoker for Cormond.
The second way to collect Ichor is to Salvage Malignant Hearts at Cormond’s workbench. This works just like salvaging gear in Diablo 4. It’s worth noting that if you salvage a piece of gear that has a Malignant Heart in it, you will get Ichor. But if you replace a Malignant Heart with another in the same piece of gear, you won’t get Ichor.
In terms of crafting Invokers, they’re very expensive. However, we do prefer to travel around with one of each type of Invoker in our consumables inventory, just so we can always take advantage of the special event in Malignant Tunnels.
