Hey. Can someone help me?

In my game, Mari killed Kudlak the way it was suposed to hapen, after the batle a message said that Mari´s demon was avaliable in cathedral of shadows. What is the cathedral of shadows? Can i really get Mari´s demon?

Cathedral of Shadows is another name for the demon fusion menu.
If it doesn't ring a bell yet - enter the COMP menu by pressing X. Choose the icon in the middle of the top row and press A to enter it.

Keep in mind that you need to be level 46 or above to be able to fuse a Kudlak, so unless you've done some heavy grinding you won't be able to fuse one right after you've unlocked him.

Can i really get Mari´s demon?
Yes, by fusing correct demons with each other. It's level 46 (same as Kudlak, in fact one of the combinations to fuse a Kresnik includes a Kudlak in it)
