Fenumus, First of the Night



Fenumus, First of the Night is one of the 4 main Spirit Beast Bosses. He is located in Fenumus’ Lair.

Boss Fight

This boss encounter is a multi part process. We will take you through how to grant access to Fenumus, how to fight him, and how to deal with the final craft that you receive after capturing them.

Accessing Fenumus’ Lair

In order to grant access to Fenumus’ Lair, you will first need to capture a Fenumal Hybrid Arachnid Beast. This beast is found randomly throughout Wraeclast. You can also pick one up over at poeapp. This beast can be identified with the following symbol:


Once you have come across this beast, Einhar will automatically capture it like any other beasts that one would encounter in the wild. The beast will be placed into the player’s Menagerie. From this point, the player will need to travel to their Menagerie and interact with The Blood Altar. On the crafting list, there will see a section called “Open a Portal…” Under this section, there is an option called “to Fenumus’ Lair.



Select this option and press the craft button. This will begin a small beast encounter where you will have to fight 4 beasts. The objective is to kill all of these beasts. After completing this small challenge, 6 portals will then be opened  to Fenumus’ Lair around The Blood Altar.  If the player dies during this encounter, the Fenumal Hybrid Arachnid Beast will be lost and must be acquired again.

Once all the monsters are slayed, 6 portals will open, granting access into Fenumus’ Lair.

Boss Encounter

When you go through one of the portals, the player will enter a small area free of monsters with a door that leads into the arena. The fight will begin once the player approaches the center of the arena.

Once he has reached a total of 50% Maximum Life, a Hallucination will be placed upon the player, causing blurred vision while minions are being summoned. The player will be teleported shortly after to a new arena to finish the rest of the fight with Fenumus.
