A practical Blasphemous 2 The Third Sin DLC access guide explaining the Lamp, double jump requirement, Choir of Thorns route, lake chariot, and Castle of the Mist entry.
Updated:
Quick Answer
To start Blasphemous 2: The Third Sin, get the Lamp of the Whisper of the Mist, make sure you have Passage of Ash for double jump, then travel to the bottom of Choir of Thorns near the Icebound Mausoleum side. From there, enter the fog route, reach the lake, interact with the chariot, choose Yes, and you will be taken toward Castle of the Mist.
Start Requirements Checklist
Before you look for the DLC entrance, check these first:
| Requirement | Needed? | What it means |
|---|---|---|
| Lamp of the Whisper of the Mist | Yes | Lets you pass the fog route toward Castle of the Mist |
| Passage of Ash | Yes | This is the double jump ability |
| Choir of Thorns access | Yes | You need to reach the lower part of the area |
| Lake chariot interaction | Yes | Choose Yes at the chariot to cross the lake |
| Finished main game? | Not necessarily | You need the movement and route access, not a separate cleared save |
Step 1: Get the Lamp of the Whisper of the Mist
The key item for the entrance route is the Lamp of the Whisper of the Mist. Start from the Our Lady of the Chalices side of the City route. Use double jump to reach the upper path, enter the room on the right, then interact with the coffin to get the Lamp.
Step 2: Make Sure You Have Passage of Ash
The entrance route expects you to have Passage of Ash, the main-game double jump ability. If you cannot reach the lower Choir of Thorns route, you are likely missing Passage of Ash.
Passage of Ash is obtained during main-game progression in Beneath Her Sacred Grounds, after the area boss route. If you do not have double jump yet, continue the main game first, then return to The Third Sin entrance path.
Step 3: Go to the Bottom of Choir of Thorns
After getting the Lamp and Passage of Ash, travel to Choir of Thorns. The important part is the vertical position: go to the bottom of the area, near the route that connects toward Icebound Mausoleum.
Do not search only on the right side at the wrong height. Choir of Thorns has several layers, and the correct route is low in the area.
The entrance route should feel different from normal Choir of Thorns cleanup because the fog and Lamp interaction become the main signal that you are in the right place.
Step 4: Follow the Fog Route
Once you are at the correct lower route, move into the fog path. The Lamp should allow you to keep going instead of being pushed back.
If the fog route still does not work, check these points before searching the whole map again:
| Problem | Fix |
|---|---|
| You do not have the Lamp | Return to the Our Lady of the Chalices side route and get the Lamp first |
| You are too high in Choir of Thorns | Drop to the lower route near the Icebound Mausoleum side |
| You cannot make the jumps | Get Passage of Ash double jump first |
| You reached the lake but cannot continue | Look for the chariot interaction |
| You are in random side rooms | Return to the lower fog route and follow it toward the lake |
Step 5: Use the Lake Chariot
After the fog route, you reach the lake crossing. Look for the chariot at the lake and interact with it. When the game asks whether you want to go, choose:
YesThis sends you across the lake toward the DLC area.
Step 6: Enter Castle of the Mist
After the lake crossing, you arrive at Castle of the Mist, the main new area for The Third Sin.
Your next real objective is not full cleanup. First, find the route toward Eliseo, then continue until the castle path leads you toward Embrujo, the new weapon needed for bells, whip points, and blue mirror-ring movement.
For the full route after entering the castle, continue with the The Third Sin Walkthrough. For the new weapon, use the Embrujo Weapon Guide.
If the DLC Entrance Still Does Not Work
Use this quick check before searching the entire map again:
| Check | What to confirm |
|---|---|
| Lamp | You have the Lamp of the Whisper of the Mist |
| Double jump | You have Passage of Ash |
| Area | You are in Choir of Thorns |
| Height | You are in the lower section, not the upper / middle route |
| Connection | You are near the Icebound Mausoleum-side route |
| Lake | You interacted with the chariot and chose Yes |
