The last one can be found on the ground near the final door. Speak with Sabastian who tells you what needs to be done. Speak with Ominis then return to Sebastian. You’ll have three options: Sebastian curses you and you don’t learn the curse, Sebastian curses you and you learn the curse or you learn the curse and use it on Sebastian. Regardless of what you choose, all three options open the door.

Speak with Sebastian afterwards regarding the relic. Either option doesn’t matter as he will grab it regardless. Exit the room to run into Ominis. Speak with him and he’ll ask you to help convince Sebastian to leave the relic. If you agree with him, this will persuade Ominis to allow Sebastian to leave with the relic. To leave the dungeon, make your way back to the room with the alter.

Afterward, follow Sebastian out of the catacomb and speak with him outside. This is your chance to learn Avada Kedavra. You’ll be prompted with two choices: “No one should know that curse” and “Everyone should know that curse”. Choosing the first one means Sebastian will not teach you the curse.
