One of the new endgame bosses for Season 2 of is the Echo of Varshan, an undead entity you have to summon by sacrificing the right items in the game's highest World Tier. By combining a Malignant Heart with three body parts, you can initiate the ritual to call upon this boss. Only the strongest characters that you've created that have a high enough level will be able to challenge the Echo of Varshan.
Varshan's boss encounter is tied to the Tree of Whispers, a place in northern Hawezar where you can complete Whisper of the Dead activities for different rewards. If you are playing within World Tier 4 in Diablo 4, you should be able to see the Malignant Burrow dungeon on your map close to the Tree. Proceed with caution if your character is at a lower level, since this location is recommended for anyone who is Level 75 or higher.
