The Burning from Within questline introduces you to Season of the Malignant's new feature called Malignant Hearts. In this quest, you will encounter Cormon after rescuing him from an odd demon. He will then teach you everything he knows about Malignant Hearts.

To gain access to this quest, you must have finished the Eternal Realm campaign or be in the midst of it on the Seasonal Realm with at least one character. When you're prepared, go to Kyovashad to meet Cormond and start your journey against Sanctuary's newest danger.

Malignant Tunnels are a brand-new dungeon with several Malignant Monsters and were first seen in Diablo 4 Season 1's Forest Clearing section. You must enter the Forest Clearing to complete the first quest, Burning from Within, which is conveniently situated northwest of Kyovashad. You'll ultimately come upon the entrance to this new dungeon as you continue to explore in that direction.

After agreeing to the mission and speaking with Vyrtan, the season quest will begin. In Kyovashad, you overheard a villager ranting about corruption. Vyrtan mentions a case of a person transforming into a demon outside the city, northwest of Kyovashad, on the way to Menestad. The character now has a new objective: find any survivors on the road.

You have to enter and search the Forest Clearing and slay the strange demon you encounter. You will notice a Malignant Heart dropping after killing the enemy. Cormond, an ex-priest, will ask to meet you outside the forest to discuss matters about the Malignant Heart.

Cormond then gives you a bag of cages to use when treating corrupted living souls. The task is finished when you return to him with the cages you used to capture Malignant Hearts.

After completing the Burning from Within, you will unlock the Plague of Hatred quest, where Cormond shows you how to use Invokers on Malignant Outgrowths that you can locate inside Malignant Tunnels. You will also learn how to make Invokers during this quest.

Burning from Within is the first part of Season 1's main storyline. It is important to finish this along with the subsequent quests to understand how the new features and gear system work in the game.


You can access the season's main questline once you reach the Epilogue of Diablo 4. Any Seasonal Character can use the new season's mechanics, including Malignant Hearts and the Battle Pass.
