Svartrau Cathedral Treasury Location in The Blood of Dawnwalker

The Svartrau Cathedral Treasury in The Blood of Dawnwalker is one of the most rewarding hidden locations in Svartrau City. Getting inside takes a bit of work — you need a specific key, and reaching the right room to grab it changes depending on the time of day. This guide tells you exactly where the Treasury is, how to get the Treasury Key, and what you will find once you are inside.

• TL;DR
• The Cathedral Treasury is in the northeastern garden of the Cathedral Complex in Svartrau City.
• The Treasury Key is inside the Cathedral Complex Belltower — a northwestern room inside the building.
• During the day, talk to the Acolyte, spend 1 hour helping him, then inspect the ledger to get the key.
• At night, Xanthe is present. Sneak in through the southeastern tower using Shadowstep to avoid a boss fight.
• Inside the Treasury: Stone Key, Phial of Xanthe’s Blood, silver valuables, and more.
• A hidden room is inside the Treasury — push the bookshelf to find it.

Where Is the Svartrau Cathedral Treasury?

The Svartrau Cathedral Treasury is found in the northeastern garden of the Cathedral Complex in Svartrau City. The Cathedral Complex sits in the eastern part of the city and is one of the most prominent landmarks in the area. The Treasury building is in the same garden as the Cathedral Complex library — both are locked structures that require separate keys.

How you reach the garden depends on the time of day. During the day, the main doors of the Cathedral Complex are open to visitors, so you simply enter through the front and exit through the northeastern doors into the garden. At night the main doors are locked, and Xanthe — one of the three vampiric vassals you need to defeat — is active in and around the cathedral. Stumbling into her before you are ready can trigger a boss fight at a bad time.

The Cathedral Complex is one of the most content-dense locations in Svartrau City. While you are in the area, the Cathedral Complex library locked door guide covers the separate Library Key puzzle in the same garden, which is also worth doing on the same visit to save time.

How to Get the Cathedral Treasury Key

The Cathedral Treasury Key is inside the Cathedral Complex itself, in a northwestern room called the Belltower. There is a ledger on a table inside that room — the key is attached to it. How you actually get your hands on it depends entirely on whether it is day or night when you visit.

Getting the Treasury Key During the Day

This is the straightforward, low-risk method. During daytime, an Acolyte — a young kid — is guarding the Belltower room. To get the key through him, do the following:

• Find the Acolyte in the northwestern part of the Cathedral interior.
• Talk to him and select “Could you let me take a look inside?”
• He will not just let you in. Choose “Maybe I could help you?”
• Spend 1 in-game hour helping him stack boxes.
• After that, you can enter the room.
• Interact with the ledger on the table inside.
• Inspect the key attached to it, then exit the inspection to take it.

The hour spent helping is the only real cost here. It is worth it given what is inside the Treasury.

Getting the Treasury Key During the Night

At night, Xanthe herself is present inside the Belltower room. Running into her triggers an early boss fight that most players are not ready for when they first visit Svartrau City. You have two real choices at night:

Option A — Fight Xanthe: If your build is strong and your Vampirism skills are developed, you can engage Xanthe and still grab the key from the ledger in the room after the encounter. This is the harder path but comes with the satisfaction of taking her on early.

Option B — Sneak in through the southeastern tower: This is the smarter move if you are not yet ready to face Xanthe. Here is how to do it:

• Approach the Cathedral Complex from the southeastern tower side.
• Use Shadowstep to climb the tower.
• Use Clawride to navigate across the rooftop.
• Work your way toward the Belltower room from above, avoiding Xanthe entirely.
• Interact with the ledger on the table and take the key.

This method requires your vampire movement abilities to be unlocked. If you have not yet unlocked Shadowstep, visit during the day instead. Our guide on how to get ability slots in Blood of Dawnwalker walks you through unlocking the Vampirism skills you need for night navigation.

Svartrau Cathedral Treasury Location — How to Get Inside

With the Treasury Key in hand, make your way to the northeastern garden. The Treasury door is in this garden. Use the key to unlock it and head inside.

Getting to the garden follows the same rules as before:

• Day: Enter the Cathedral Complex through the main doors and exit via the northeastern doors into the garden.
• Night: Climb the Cathedral Complex Scouting Tower and use Clawride to descend from the northern edge into the garden — or use the route via the Svartrau North East Shrine, head behind the Blacksmith, enter the southeastern metal gate, Shadowstep to the roof, and drop down.

What Is Inside the Svartrau Cathedral Treasury?

The Treasury has two sections — the main room and a hidden area behind a secret wall. Make sure you explore both.

Main Room — Chests and Bookshelves

When you first enter, open all the chests and search the bookshelves along the walls. The bookshelves contain silver valuables — bowls, chalices, and other items that can be sold for Denarius. These are well worth grabbing. Silver sells well but requires access to the Silver Trader in Svartrau City’s Altenmarkt district. Our Blood of Dawnwalker silver selling guide explains how to unlock him if you have not already done so.

The two most important items found inside the Cathedral Treasury are:

• Phial of Xanthe’s Blood — a legendary consumable you can drink to unlock the Blood Surge Ability in the Vampirism Skill Tree. This is a powerful vampiric ability and one of the better reasons to visit the Treasury early.
• Stone Key — a key item used in a completely separate quest. More on this below.

The Hidden Room — Behind the Bookshelf

This is the part many players miss. Inside the Treasury, look for a bookshelf that can be interacted with. Push it and it will slide aside to reveal a hidden room behind the wall. Here is what to do:

• Push the bookshelf to reveal the hidden passage.
• Climb the ladder down into the room below.
• Open the hatch at the bottom.
• Use Focus Mode to highlight all interactive items in the area.
• Inspect the yellow/golden-hued items that glow in Focus Mode.
• The Stone Key is on a stone in front of a cross in this hidden section.

Do not leave the Treasury without finding this room. The Stone Key is a key item that connects to another quest and leads to one of the game’s legendary weapons.

What Is the Stone Key Used For?

The Stone Key you find inside the Cathedral Treasury hidden room is used during the A Hero’s End quest. It unlocks a hidden coffin inside an Ancient Ruin, and inside that coffin you will find:

• The Hand of Fate — a legendary sword.
• An Ancient Ring — an accessory with strong passive bonuses.

You do not strictly need the In the Name of the Father quest to access the Ancient Ruin. There is an Ancient Key on a barrel next to Father Florin that can also open the ruin entrance — so you can get there either way. But the Stone Key from the Treasury is what unlocks the specific coffin inside that holds the legendary rewards.

Hold onto the Stone Key and do not accidentally sell it. It has no value as a sell item and its only purpose is unlocking that coffin during A Hero’s End.

What Is the Phial of Xanthe’s Blood?

The Phial of Xanthe’s Blood is a legendary consumable that unlocks the Blood Surge Ability in Coen’s Vampirism Skill Tree. Blood Surge is a powerful vampiric ability that enhances your nighttime combat. Drinking the phial is how you access this ability — you cannot buy or earn it any other way in a standard playthrough.

This makes the Cathedral Treasury one of the most important optional locations in the game for players who want a strong Vampirism build. If you are building toward night combat, grab this phial as soon as you can reasonably visit the treasury. See our guide on the best skills to level up in Blood of Dawnwalker to understand where Blood Surge fits in the broader skill progression.

Tips for Visiting the Cathedral Treasury

• Visit during the day if you want the simplest route. The Acolyte method costs 1 hour but is far safer than navigating around Xanthe at night without strong Vampirism skills.
• Do not skip the hidden room. The bookshelf-concealed area is easy to miss and contains the Stone Key, which matters for a later quest and a legendary sword reward.
• Use Focus Mode inside the hidden room. The key items glow yellow/gold when Focus Mode is active — without it, they are easy to overlook.
• Grab the Phial of Xanthe’s Blood before drinking it. Make sure your Vampirism Skill Tree has the slot available for Blood Surge before consuming it so the ability unlocks straight away.
• Loot all the bookshelves in the main room for silver valuables. These are worth selling at the Silver Trader in Altenmarkt for a good chunk of Denarius.
• Save before the night visit if you plan to sneak past Xanthe — one wrong step can trigger a boss fight you might not want right now.
• Collect both keys on the same trip if possible. The Treasury Key and the Library Key (in the adjacent library building) are in the same garden. Handling both on one visit saves time segments.

If you are working through Svartrau City’s content in order, the Echoes of Silenced Bells quest is a major companion questline that also unlocks important gear and skill manuals — a great activity to pair with your Svartrau City exploration before or after the Treasury visit.

For players also managing Coen’s vampire abilities and wanting to maximise the value of the Phial of Xanthe’s Blood, our guide on how to unlock Eclipse Edition DLC content covers additional ability upgrades available in the game.
