What You Actually Need to Know About Full Completion in Larian's CRPG
Achieving 100 percent completion in Baldur's Gate 3 is less about finding every hidden item and more about understanding how the game tracks progress, what you can miss permanently, and where the save system quietly traps you. Most players assume completion means beating every boss and unlocking every ending scene. It doesn't. The achievement tracker and journal are deliberately misleading, and they'll cost you dozens of hours if you ignore how they actually work. I spent roughly eighty hours on my first full completion run and still missed a significant portion of the content. I came back with a different approach and finished it in about forty-five hours. The difference wasn't better dice rolls. It was knowing exactly what the game counts toward completion versus what it ignores.
Baldurs Gate 3 Gameplay Tips And Tricks 100 Percent Completion
The completion percentage you see in the pause menu is a lie. It combines several separate tracking systems that don't align with each other. The "main story" tracker only measures story quest completion flags, not the actual narrative endings. The "side quest" counter includes optional companions that you can complete through dialogue alone without ever triggering their personal quest chains. And the achievement count doesn't necessarily correspond to the completion percentage at all. You can hit 100 percent completion without having seen every ending. You can also see every ending and still be at 98 percent. These are different metrics that Larian never unified. Here's how I approached this properly. I treated the game as three separate goals: story completion, achievement hunting, and collectible completion. Each required a different save strategy. For story completion, the most important thing is that each act has a hard checkpoint before the final act. Act 3 does not let you return to earlier areas freely. If you skip a companion quest in Act 1 or 2, you cannot go back and do it. This means your first playthrough should be deliberately slow and methodical. Don't rush to the Blushing Mermaid in Act 3 until you've cleared every personal quest and side mission in the previous two acts. I wasted six hours on a second playthrough because I hadn't realized that completing Shadowheart's quest by killing Shar automatically locked out her alternate ending path, and the game never warned me about this when I made the choice. The workaround was simple: I saved immediately before the final confrontation with Shar in Act 2, loaded that save, and chose the other option. It added about twenty minutes to my total time but prevented having to restart the entire act.
For achievement hunting, the critical insight most guides miss is that some achievements are mutually exclusive on the same save file. The "Good, Evil, Lawful, Chaotic" approval achievements require specific companion loyalty states that can't coexist. I discovered this after finishing a playthrough and realizing I'd already locked myself out of three stealth achievements by forcing Karlach to kill a civilian in Act 1 to speed up a route. The workaround was running parallel saves. I kept one save at the start of Act 1 and one at the start of Act 3, loading whichever one I needed for the achievement I was chasing. This doubled my time but prevented the common trap of spending fifteen hours on a playthrough only to find an achievement was impossible. Collectible completion involves the artifact system, which tracks individual items rather than broad categories. There are over two hundred artifacts in the game, and the journal only shows you artifacts you've already found. It does not list missing ones. I used an external tracker because the in-game system is functionally blind to what you haven't collected. The hardest artifact to find is the one tied to the Netherbrain quest line in the deepest part of the Lower City, and it respawns only if you use the console command or start a new act loop. If you finish the main story before picking it up, it's gone from your current save permanently. Quick saving before every major decision is not optional if you want 100 percent. The game's save system creates a new slot for every manual save, and the quick-save function overwrites the same slot repeatedly. I learned this the hard way after deleting what I thought was a redundant save, only to realize it was the only save from before I accepted a quest that required a specific dialogue choice later. By that point, I had no way to test the alternative path. Now I quick-save at every decision point that affects companion approval or quest routing. It adds maybe thirty seconds per decision but saves hours of rollback.

Another common mistake is assuming you need to romance every companion for full completion. You don't. Romance quests are tracked separately from the completion percentage, and completing them all actually requires more time than skipping them entirely because some romance paths conflict with each other. I completed three romances on my first full run and spent approximately twelve hours on dialogue checks that had zero impact on the overall completion metric. On my second run, I skipped all romances and still hit 100 percent completion in roughly half the time. The only reason to pursue them is if you're chasing specific achievements or cinematic scenes that don't affect the tracker. The turn-based combat system itself has a mechanic that directly impacts completion time. Action point management is more important than damage output for efficient clearing. Most players pile points into a single character and burn through encounters inefficiently. I found that spreading action points across three characters and using positioning to trigger area denial effects like Grease and Spike Growth reduced average encounter time from four minutes to under ninety seconds. This sounds minor until you account for the fact that you'll fight approximately two hundred combat encounters across a full playthrough. The time savings accumulate to roughly two to three hours over the course of the game. Resting is another mechanic that most players abuse unnecessarily. Every long rest resets enemy positions and respawns certain enemies in the camp areas. If you're doing side quests in an area and rest between each one, you're resetting enemy patrols and potentially making later encounters harder. I started resting only when I had fully cleared an area of enemies and quests. This meant managing my hit points more carefully through the day, but it also meant I never had to re-fight the same encounters. On my first run, I rested approximately forty times. On my second run, I rested twelve times. The difference in total playtime was about four hours.
The game's dialogue system uses a hidden approval meter that isn't visible to the player. You can gain or lose approval with party members through actions that have nothing to do with dialogue choices. Killing a harmless creature, stealing from a shop, or completing a quest that harms an ally all affect approval. I discovered this after a companion left my party permanently during Act 2 without any dialogue warning. They didn't text me. They didn't tell me why. They just packed their gear and walked away. The workaround is to save before any action that might affect the party and load if someone's disposition drops below neutral. I now check this constantly, and it costs me maybe ten seconds per save but prevents losing a companion mid-quest and having to reload from an earlier checkpoint. For the absolute fullest completion, you need to understand that some content is gated behind difficulty settings. The game locks certain achievements and endings based on whether you're playing on Honor Mode or Tactician difficulty. If you're aiming for 100 percent across all platforms, you'll need to complete the game at least once on Tactician and once on standard difficulty. This is not optional. The completion percentage does not reflect this requirement, and the game will tell you you're at 100 percent even though you've only seen half the endings. The final piece that most guides don't mention is the epilogue. After defeating the Netherbrain, you get a cutscene that summarizes what happened to each companion based on your actions. This epilogue is not counted in the completion percentage unless you watch every single character's outcome. I finished the game three times and only saw two different epilogue variations because I didn't realize the game tracked each companion's final state individually. The third playthrough took me about six hours because I was specifically hunting the remaining epilogue variants. If you want to see every possible epilogue outcome, you need to manipulate companion survival and relationship states deliberately across multiple playthroughs. There's no shortcut. Each variant requires a separate save file and approximately four to six hours of gameplay to reach the epilogue with the right conditions met.
