The Bestiary is a log system in Diablo Immortal that displays sketch artwork of enemies, including a brief lore-based description. These logs include both common and unique mobs found throughout the world of Sanctuary. Filling out these records is an excellent way for casuals and completionists to immerse themselves by learning more about the monsters they’ve slain. However, the Bestiary is not only for show, as players will also gain substantial rewards and bonuses in Diablo Immortal for unlocking entries within the book. These rewards include XP, Gold, and even random pieces of equipment. Accordingly, knowing how to complete the Bestiary in Diablo Immortal is essential for heroic adventurers.
Completing Entries in the Diablo Immortal Bestiary
To complete the Bestiary in Diablo Immortal, players must collect a Quest Item known as Monstrous Essence. This Quest Item is a potential drop from random mobs found throughout the open world but not in Dungeons. Once adventurers procure Monstrous Essence ×10, they will be able to visit a device known as the Horadric Altar to unlock a random entry.
However, before players can begin unlocking Bestiary entries, they must first gain access to the Horadric Altar, a small pulpit that holds the tome of logged enemies. This altar becomes available after completing “The Horadric Bestiary,” the fourth quest during the Dark Wood storyline. Players will reach the Dark Wood during the main campaign between Levels 20 to 29. During “The Horadric Bestiary,” players are tasked with speaking to several NPCs and slaying multiple Demons. Afterward, they will receive access to the Bestiary tome atop the Horadric Altar in Westmarch. By delivering Monstrous Essence to the tome, players will unlock a random page and receive a batch of rewards. This delivery can be conducted up to three times a day.
One of the best locations to farm Monstrous Essence to complete the Bestiary in Diablo Immortal is the Hermit’s Outpost in Bilefen, a zone that adventurers will reach around Levels 40 to 45. This area has multiple groups of mobs packed together in close proximity. Therefore, it’s an excellent spot to acquire tons of loot drops, XP, and the essence. Alternatively, another worthwhile activity for farming Monstrous Essence is completing Bounties on the Bounty Board. This activity allows players to both earn Bounty rewards in Diablo Immortal and Monstrous Essence at the same time.
