Blasphemous 2

This requires the player character to acquire the figures for both Cástula and Trifón.

To do this, you have to first provide one of them with a specific item.

For Cástula you will need Scroll of the Elder (Trifón's Manuscript) from the Crown of Towers. Beginning at the Prie Dieu at the entrance to the area, head to the right until you reach an area with platforms that form a staircase to an upper platform; it should be the third room from the Prie Dieu. Ascend the platforms to find a statue. Interact with it and the platforms will all rise to form a line - quickly make your way across this to reach a vertical shaft with climbable walls on either side, avoiding a fire ball looping the area. The manuscript can be found at the top.

For Trifón you will need Cloth of the Old Woman (Cástula's head scarf) from the Sacred Entombments. To acquire this item, you'll need to complete a platforming challenge on the screen to the right of the topmost Prie Dieu. You'll need to first unlock this by walking through the ghostly door to the right after hitting the bell in the chasm with Veredicto. Keep in mind that you will also need Sarmiento & Centella to reach the platform.

After acquiring one of the two items, head to the Prie Dieu at the top right of Palace of Embroideries; Cástula and Trifón can be found two rooms to the left of this spot. Only one will be available at any given time to interact with. If you don't have the item for whichever is available, leave the room from the opposite side you entered and come back in from that side. The other should then be available to interact with.

Speak to them until you are given the option to give them their requested item. This will lead to more dialogue and will give the player their sibling's remembrance. From then on, the other sibling will be impossible for the player to interact with, which is why you only need to acquire one of the two items. Instead, the opposite remembrance will then be available for purchase from the vender in the Forlorn Patio for 6,000 marks.

After both have been acquired, access your Altarpiece of Favours and put Cástula in the left side of a pair and Trifón in the right of that pair. The achievement should unlock immediately.
