The Assassin’s Creed Valhalla Mad Monk’s Lair is a key location you’ll discover while exploring Suthsexe. This specific landmark featured in the latest Assassin’s Creed video game developed by Ubisoft is also tied to a Mystery you must complete, and in the following guide, we’ll discuss both the lair and the Mad Monk you’ll have to deal with.

The quest is named A Prayer for Vengence, and as usual, this World Event must be completed to get 100% completion in Suthsexe. Once you do that, you can fully explore the Mad Monk’s Lair.

AC Valhalla A Prayer for Vengence World Event Location

As you can see on my map below, the Monk’s Lair is located southwest of  Chertsey Abbey Ruins; however, on the same map, you can also see that I have marked the location of the World Event you should complete first. The idea here is to finish A Prayer for Vengence event, deal with the Mad Monk, and only then explore the Mad Monk’s Lair.

So, first head to the location of the said Mystery, and here you’ll find a tomb. Now, you’ll want to find a way inside, and since the main entrance is blocked, simply go around the tomb to spot the window in my picture below.

Shoot an arrow through the window and aim for the crate on the other side. Next, head back to the main entrance and push the shelf to get inside. While inside the tomb, start looting everything. Here is what you can find:

  • Monk’s Lair Chest Key – on a piece of cloth on the ground
  • Opal – found on the right side next to a drawing on the wall
  • To God and The Many Martyrs Note – near the small window mentioned above
  • Leather & Ore – inside the chest
  • Titanium – next to the pile of wood

Dealing With The Mad Monk

Once you get all these items, it’s time to get out of the tomb, except that the Mad Monk who owns the place won’t let you escape. Your goal here is straightforward. Kill the Mad Monk, who is a very accessible target. You can see him below.

After you kill him, A Prayer for Vengence ends, so head to the Mad Monk’s Lair on my map above.

Exploring The Mad Monk’s Lair

To get inside the Mad Monk’s Lair, you don’t need a Monk’s Lair Key because the door is wide open, so start looking around to find the following items, which are the most important:

  • Nickel Ingot – by the door (requires the Monk’s Lair Chest Key you already got from the tomb)
  • Suthsexe Hoard Map – on the ground in the corner of the house

Once you clear the area, all you have to do is focus on finding the Suthsexe Hoard Map.
