Start with an exploration save and read Three keys beneath Paris before setting off. In Roadmap, the five chapters are stages of this route, not separate in-game chapters. Read the current section before moving on, then use its linked trophy solutions for the exact puzzles, pickups and fight instructions. Trophies is the lookup view for individual entries. Open hidden details when you are ready to read them.
I’d leave the timer alone on your first trip through Paris. You need the three keys beneath the city, the movement upgrades inside the castle and several optional arcana before every room is reachable. Save at each Mirror of Life and take the weapon lying beyond a boss when you see one. Those two habits save a lot of backtracking.
First save, story and endings. Follow Chapter 1 and Chapter 2 to the large green clock. Take the trapped route for Belmont’s fall, choose Resume, then use Soul Harvest at the clock to reach the real final fight for The hunt goes on. Resume the same file and follow Chapter 3 through the four virtue trials. Read Curse lifted before repeating the final fight because its ending needs a spell at the right moment.
First save, collection. With your movement abilities unlocked, sweep one district at a time using Chapter 4. Its linked solutions cover the weapons, heart fragments, clues and mirrors. Rotate arcana while you travel so you can earn blessings on the way to the save file’s 100% rating. The optional MapGenie map and tracker are linked there if you want help marking pickups.
Second save, speed. Keep the exploration file and start in an empty slot. Follow Chapter 5, with the organ notes in Chapter 2 handy. Dialog Skipper requires the real rooftop boss before four hours. The bad ending is not a shortcut to that trophy.
