What are all the quests/bosses required to do all the imbuements?

Question

I want to be able to do ALL the imbuements. What are the quests/bosses I must complete to be able to do so?

Answer 1

There are two ways to obtain Powerful Imbuements. First is completing Forgotten Knowledge Quest, where you can gain all possible imbuements and second is completing Heart of Destruction Quest, which awards us with 3 imbuements.

I have killed World Devourer but not Last Lorekeeper and I have Power Epiphany (Magic level).
Must be from completing Heart of Destruction, right?
