What 100% Completion Actually Looks Like in BG3
Getting to 100% in Baldur's Gate 3 is not a sprint. It is a multi-session commitment that takes most players between 150 and 200 hours if they are being thorough. The completion meter tracks journal entries, quests, areas explored, and a few other things, but the breakdown is not straightforward. I spent about 180 hours on my first full completion run, and I still missed a handful of things on the second pass because the game does not tell you what it is counting. The core method is simple: go everywhere, talk to everyone, and save obsessively. That is where people go wrong immediately. They think they need multiple saves per area, but what actually works is a structured save rotation. I keep three saves per act: one at the start of the act, one midway, and one before any major decision point. When the game gives you a new area or triggers a quest flag, I backfill the save. This costs time upfront but saves you from backtracking three hours to pick up one missed side quest. The journal is your primary tracking tool, but it is incomplete. It does not track exploration percentage per area, and it does not flag every collectible. I used an external checklist from the Larian forums that listed every documented objective. Not everything on those lists shows up in-game, which is confusing, but the overlap is about 90 percent. Things like Companion Personal Quests, the Githyanki Crèche, the Moonrise Towers sequence, the Underdark routes, and the various faction camps each have their own sub-requirements.
One thing beginners miss completely is that 100% is not a single number. There is the Story Completion percentage, the Exploration percentage, and the Achievement unlock count. You can hit 100% on story and exploration and still not have 100% of achievements because some require specific choices that are mutually exclusive. Shadowheart becoming a Dark Justiciar locks out the "Light in the Darkness" achievement. Minthara staying alive locks out certain companion approval thresholds. These do not reset between playthroughs unless you load a prior save. I encountered a specific issue on my third attempt where the completion counter was stuck at 97 percent despite having finished every quest, explored every map, and talked to every NPC. The problem was two hidden journal entries tied to the Owlbear Pup questline. If you side with the owlbear during the goblin camp encounter and do not return to its den afterward, one entry never triggers. The workaround is to visit the owlbear den at least once after completing the goblin camp, regardless of which path you took. The game requires a check-in event, not just a resolution flag. Another edge case involves the Raphael contract side quests. Several of them are optional and can be completed in different orders. If you complete too many in one session without saving between each one, you risk soft-locking yourself out of certain options because some choices affect dialogue availability later. My approach was to complete one Raphael quest per act and save immediately after each resolution. This took more real time but avoided reloads.
The Act 3 city exploration is the biggest time sink. Baldur's Gate has multiple vertical layers, hidden passages, and locked doors that require specific keys or spells. Some areas only open after certain story beats. The Underdark alone accounts for roughly 20 to 30 hours of exploration if you are doing everything. There are secret rooms behind illusion walls, underwater passages, and teleportation circles that lead to hidden zones. I spent about twelve hours just mapping the city properly on my second pass. Companion approval affects more than just romance. It affects quest availability and ending variations. Astarion requires high approval to unlock his personal quest completion. Karlach needs approval to access her endgame resolution. Lae'zel's approval gate is less strict but still matters for her final conversation. If you ignore companions entirely, you will miss several journal entries tied to their arcs. The true 100% also requires collecting every artifact, tome, and journal entry. Some books are in chests that require thievery checks above 20. Some are in areas you can only access by killing bosses. The Gale companion quest has multiple branches that produce different journal entries depending on whether you help him, ignore him, or confront him about the Crown of Karsus.

There is no shortcut to 100%. Mods exist that add completion trackers, but they are unofficial and can break with patches. Larian's own tracker is unreliable past Act 2. If you want accuracy, you need a manual system. The process usually takes two to three full playthroughs if you are doing everything, or a single run with extensive reloading. I recommend at least one full run focused purely on progression, then a second run dedicated to clearing out missed objectives. The third pass is for achievements and any conflicting choices you avoided the first time. The main downside is that some content becomes unavailable based on earlier decisions. You cannot undo a decision to side with the Absolute cult without loading an earlier save. Some players report that the game lags significantly in Act 3 once you have accumulated dozens of journal entries and quest flags. My experience confirmed this. Frame rates dropped from a stable 60 to around 35 on mid-range hardware after completing the Act 3 campaign with all side content. Saving frequently helps, but it does not fix the performance hit. If you are willing to invest the time, 100% completion is achievable. It requires patience, a solid save strategy, and the acceptance that some content will be locked behind choices you made hours ago. There is no way to see everything in a single playthrough unless you are comfortable with reloads. Most players who claim otherwise are either using mods or have not actually checked every requirement.
