I don't think that is necessary to do those things to obtain the "Exalted" Trophy. I'm trying some stuff into the game, and I play many walktrough ( around 3-4 times ), so I think that trophy is bugged for the most people (including me). Then I search into the Twitter's account of Sinner: Sacrifice of Redemption and I discovered that many trophies are bugged. The team is working on a patch that comes in few days, so we have to waiting. Adam is most powerful when he buffed, the trophy is obtained from someone casually.
Sorry for my english but isn't my first language.
