MISSABLE TROPHYFor this trophy you must perform specific actions and specific final choice in order to get it.
*** Spoiler - click to reveal ***During main story mission where you visit Celene you must gain 100 approval. You can do it by exploring and interacting wit guests within the palace. When you will be given an important choice towards the end of the mission you must publicly accuse her. You don't need to have 100 reputation at that moment but you need to get there once. As for me during last scenes of fights my reputation dropped to 98 but I still got the trophy.
