You can collect Monstrous Essence as a random drop from defeating monsters throughout the world. However, this drop rate can be low, so you may need to farm monsters. Or, you can opt to passively collect them by simply playing through the game and gathering them when they drop. Using a strong PvE class will speed this process up.

How to unlock the Bestiary

You will unlock the Bestiary as part of the main quest, specifically The Horadric Bestiary quest in the Dark Wood. You must interact with an altar where a tome is resting. This is the Bestiary, and it will now be added to your menu.
