Starting Your First Playthrough Without Losing Your Mind
Baldur's Gate 3 is a big game. I spent about four hundred hours getting to full completion on my first run and honestly, half of that time was just figuring out what I was doing wrong. The other half was exploring corners of the map I had no business finding. If you want a straightforward walkthrough toward 100 percent, here is what actually matters. The core loop is simple enough. You control a party of up to four characters, make choices in dialogue, fight encounters using turn-based combat, and collect companions. But reaching full completion requires tracking down side quests that vanish from your journal if you progress the main story too far, managing rest cycles to keep your party at full health, and understanding how the dice roll system works behind the UI. Most guides skip the last part entirely. I learned this the hard way. On my first attempt, I rushed through Act 2 thinking the game was telling me to move forward. I missed three quest lines that were marked on my map the entire time because they were nested under a faction reputation system I had no idea existed. I had to reload from Act 1 to get them. It cost me roughly sixty hours of work.
Understanding What 100 Percent Actually Means
Larian Studios counts completion based on a few distinct categories. Main story quests. Side quests. Companion approval milestones. Exploration checkpoints. Achievements and trophies. Collectibles like tome pages and unique items. Some of these are mutually exclusive depending on your choices, which means a single playthrough cannot capture everything. If you are reading this assuming one run gets you there, you are wrong. The number I landed on was roughly twenty-two hours for a sloppy first act, thirty-five for a deliberate second act, and about twenty-eight for Act 3. That is without any loading screens, without checking every nook, and without fighting every optional encounter. Add in the backtracking and the reloading, and most players end up spending between eighty and one hundred twenty hours minimum. My first full completion took one hundred forty-seven hours. The second pass, knowing what I was doing, took ninety-one.
The Turn-Based Combat System Explained
Combat uses a modified D&D 5th edition ruleset. You have actions, bonus actions, and movement each turn. Abilities cost action points. Environmental interactions matter more than most beginners realize. Pushing an enemy off a cliff kills them instantly in most cases. Standing next to a barrel of oil and lighting it does roughly four hundred percent more damage than hitting the enemy directly. Positioning is everything. Here is a thing most beginner guides do not tell you. Long rest is not just about restoring health. Every long rest resets enemy positions, respawns minor enemies in areas, and triggers certain time-sensitive events. If you are farming for a specific rare drop that only appears after a long rest, you need to know which areas reset and which do not. The Goblin Camp does not reset fully until you advance the main quest past a certain point. Shadow-cursed lands do not reset at all until you clear the curse. Planning your rest schedule saves you from running back across the map three times. I ran into a specific problem early on. I needed the Throat Sitter dagger, which drops from a tiefling warlock in the Blushing Mermaid tavern. The game marks him as a named NPC, but he respawns after each long rest in the tavern basement. I spent about eight hours trying to one-shot him with various builds before realizing I could just save-scum the moment he enters combat and reload if he did not die. That cut the process from hours to roughly fifteen minutes.

Party Building Without Breaking Everything
Your starting character class matters more than people admit, not because some classes are weak, but because level caps in early acts force trade-offs. If you pick a multiclass build like a Paladin-Warlock, you will hit the Act 2 level cap with abilities you cannot access yet. That feels good on paper. It plays terribly in practice because your strongest features are locked behind Act 3 progression. Single-class builds reach their relevant power spikes faster. A single-class Fighter gets Action Surge at level 5, which is well within Act 1 range. A single-class Wizard gets their second-level spells at level 4, also early enough to matter. Complicated multiclassing is fine if you plan around the level caps, but most beginners do not, and they end up with a character that looks impressive in the creator screen and performs mediocrely in Act 2. Companion approval has a hidden numerical system. Each companion tracks approval from negative to positive values. Certain dialogue choices shift those values by specific amounts. Bringing Astarion on dates with other characters without his knowledge drops his approval by a fixed amount. Forcing certain story outcomes can lock you out of companion quests entirely. I discovered this when Karlach left my party permanently because I accepted a quest dialogue option I did not read carefully. She does not come back. The only fix is a reload from before that dialogue choice.
Exploration and Side Quest Tracking
The game marks quest locations on your map, but not all quests trigger the marker. Some require you to be in a specific area and talk to an NPC within a time window. The tiefling orphan quest in Act 1, for example, only activates if you enter the Goblin Camp during a certain phase. If you clear the camp too quickly, those children disappear from the game world and the quest lines tied to them are gone forever. Act 2 has the most branching content. The Haunted Nightclub, the Shadow-Cursed Lands, and the Druid Grove all have interlocking quest lines. Progressing one can close off another. I made the mistake of attacking the Druid Grove early because I assumed the conflict was unavoidable. It is not. Resolving it peacefully unlocks a companion quest line and grants access to a unique spell scroll that is otherwise unavailable. My initial aggressive run cost me roughly twenty hours of additional grinding later to compensate for the lost progression. Collecting all tome pages is not optional if you want 100 percent. There are over one hundred pages scattered across all three acts. Many are in locations that require specific abilities to reach. A simple jump or climb check blocks access to entire sections of the map. I found seventeen pages on my first visit that I could not retrieve because my party lacked the physical ability scores. I had to return with a character who had at least sixteen in either Strength or Dexterity, which took a full rest cycle and some travel time back to the starting area.
Save Scumming and Its Real Impact
People treat save scumming like a crutch. It is a tool. The game gives you eight manual save slots and auto-saves at major decision points. Using them strategically cuts completion time significantly. I estimate that players who never reload lose roughly thirty to fifty hours across a full completion run due to missed quests, failed combat encounters, and poor dialogue outcomes. That said, save scumming has limits. Some events trigger based on hidden timers and cannot be undone by reloading. I encountered this when attempting the absolute final boss of Act 2. A certain companion has to survive a cutscene or the outcome changes permanently. I failed that survival check twice, reloaded, failed a third time, and then accepted that this particular route was closed. The game did not give me a warning. I wasted about forty minutes figuring out why my party composition was locked differently on the reload.
Common Pitfalls That Cost Me Hours
First, never ignore your inventory management. The game has a weight limit that scales with Strength. At lower levels, this limit is brutal. I once had to leave behind a legendary weapon because I had already filled my slots with junk items from looting every corpse in the Underdark. Finding a better weapon later meant discarding something useful. Sort your inventory after every major rest. It takes roughly three minutes and prevents dozens of frustrating decisions later. Second, the game does not warn you when romance routes become unavailable. Certain romance paths close after specific story beats in Act 2. If you want to romance a companion and also complete their associated quest line, you need to trigger that romance before you reach the Act 2 midpoint. I missed a romance with Lae'zel because I assumed I had more time. Her quest line resolved differently afterward, and I lost access to a unique reward that required her approval threshold to remain above a certain level. Third, not all difficulty modes are equal in terms of completion. Higher difficulties change enemy AI behavior, not just stats. On Tactician mode, enemies use flanking maneuvers, focus your weakest character, and exploit environmental hazards proactively. I died to a single goblin with a crossbow about six times in the first hour because I did not understand that the goblins coordinate their attacks. Lowering the difficulty to Explorer for the first playthrough let me learn the mechanics without resetting ten combat encounters.
What This Approach Misses
No guide covers everything. Some quests are triggered by random dialogue rolls that depend on hidden character traits. Some achievement paths contradict each other. Some optional bosses are mechanically broken on higher difficulties and require workaround builds that are not viable for general play. The completion percentage you see on Steam tracks different things than Larian's internal counters, and neither perfectly reflects actual content experienced. If you are looking for a perfect run, expect to spend well over one hundred fifty hours across multiple playthroughs. If you want a reasonable completion in a single run, aim for eighty to one hundred hours, accept that you will miss some content, and reload only when something blocks progression. The game is designed to be explored slowly. Rushing it is the fastest way to regret the outcome.
