Gamers have hours of content to pursue outside the main story in Kingdom Come: Deliverance 2. Every town has at least one side mission or task that players can complete to earn gold, a good reputation, or new skills. Opus Magnum, however, is a side quest that happens to tie into the main story.
Opus Magnum can be long or short, depending on the order in which players decide to do things in the story. For those looking to tackle it, here's how to complete Opus Magnum in Kingdom Come: Deliverance 2, along with a rundown on all possible outcomes.

How to Start Opus Magnum in Kingdom Come: Deliverance 2
Players will pick up Opus Magnum from the Miller in Lower Semine. The Miller is a part of the Wedding Crasher's main quest, and going to him will eventually get Henry an invitation to the wedding. However, players can also go to the wedding through the Blacksmith's questlines and still have a chance to pick up Opus Magnum.
Go to the Miller Before the Wedding
Opus Magnum will be longer if players go to the Miller before the wedding. Lower Semine is south of the central city. Here, players will notice that it is full of shady characters, including Miller Kreyzyl. The following quests must be completed before they can start Opus Magnum:
Opus Magnum will begin right after Forbidden Fruit has been completed.
How to Complete Opus Magnum in Kingdom Come: Deliverance 2
Kreyzyl needs Henry to get his hands on a book at Trosky Castle, so players must go to the wedding and get access to Trosky. The Miller will send Henry as a chaperon to a young woman who will seduce the Chamberlain from Trosky.
Players must buy a red dress and also get Henry's wedding clothes from the Tailor in Troskowitz. They will also need Mintha Perfume.
Players should aim for a Charisma stat of 15 or higher and dress Henry from head-to-toe.
How To Repair Bows & Crossbows In Kingdom Come: Deliverance 2
Bows and Crossbows can't be repaired at the same places as weapons and armor in Kingdom Come: Deliverance 2; here's where to repair them.
Next, head to Zhejelov and talk to the bathhouse maids at the Inn and talk to Dorothy. The girls will refuse to help because of the Chamberlain's odd preferences when using bathhouse services. Thankfully, Dorothy will give Henry a tip about a Nomad girl who may be willing help him.
Go to the Nomad Camp and find Enneleyn. She will be at a broken-down cart north of the Nomad's camp. Players must give her the red dress, Mintha Perfume, and be wearing their wedding clothes during this encounter. Then, they can start Wedding Crashers.
Players will need to complete several main quests before they can finish Opus Magnum, including the following:
After finishing those quests, Henry will be released back into the world. Players should then return to the Lower Semine Mill and finish Opus Magnum before they visit Hans for the party in For Victory!
Where to Find the Book for the Miller
Players can also visit the Miller and start Opus Magnum after they reach Necessary Evil. For this approach, they will still need to finish Materia Prima and Forbidden Fruit. They will skip the first half of the quest but will still need to find the book at Trosky for the Miller.
The Miller will suggest that Henry ask Scribe Erazim at Trosky Castle about the book. Erazim is usually inside the Scribe's chamber in the Crone's Tower. When players ask the scribe, he will send Henry on a wild goose chase to ask about a Noble named Nikvard, a character who had the book last. None of the people he tells Henry to ask will know Nikvard's exact location, but they will give Henry enough hints to help him find the book.
Nikvard is lying dead outside of the castle walls on the west side of Trosky Castle. Players will find him right below one of the castle towers with a man standing next to his body. The book isn't on his person; it is instead lying a few feet away, near the castle wall.
Henry must then take the book back to Miller Kreyzyl. Once Henry asks him the next steps, Kreyzyl will tell him to meet him at the Lair, where he will explain everything.
The Lair is south of the Mill and will be marked on the map. A cutscene will begin to play when Henry is close enough, and the side quest will end there. Upon completing Opus Magnum, players will be rewarded with the 
Recipe for Lead Shot Gunpowder.
