BG3 Missable Content Checklist — Interactive Per-Act Tracker

Baldur's Gate 3 is packed with companions, quests, and unique items that quietly disappear if you advance the story without triggering them. This interactive checklist covers every confirmed missable per act — toggle a tab, check items off as you go, and your progress is saved automatically in your browser. Items are drawn from the Baldur's Gate 3 wiki and extensively cross-checked community guides; BG3 also carries the alternate name Baldur's Gate III.

01Interactive Missable Content Checklist

02Act 1 — What You Can Miss and Why

Act 1 is the largest and most open act, but it has a hard stop: the moment you cross the bridge into the Shadow-Cursed Lands for Act 2, you cannot return to the Wilderness. Every companion, quest, and item on the Act 1 tab must be resolved before that transition.

Companions: Wyll is easiest to miss — he stands inside the Emerald Grove near the training dummies. Karlach is north-east on the Risen Road; letting her paladin hunters kill her or raiding the Grove before talking to her locks her out. Withers is not a combat companion but unlocks free respec from camp, which matters enormously for optimising builds.

Unique events: Auntie Ethel's Hair is the single most potent permanent upgrade in Act 1 — you must reduce her HP below 20% in battle before she flees, at which point she offers it as a bribe. Skipping this costs you a permanent +1 to any ability score. Playing a musical duet with Alfira at camp is a missable scene — she is absent if you raid the Grove or fail to save the Tieflings — so trigger it before crossing into Act 2.

Volo chain: Rescue Volo from the Goblin Camp (he's in a cage near the performance area) before completing 'Save the Refugees.' He moves to your camp and later performs crude eye surgery, giving you Volo's Ersatz Eye — a permanent See Invisibility effect that works all game.

Items: The Everburn Blade is only obtainable in the Nautiloid prologue by using Command: Drop on Commander Zhalk and looting it from his body. Once the prologue ends, it is gone forever. Phalar Aluve requires either Strength 18 or a Religion 15 check to pull from the rock in the Underdark — an easy miss if you rush past it.

03Act 2 — The Shadow-Cursed Lands

Act 2 is shorter but more tightly scripted around Last Light Inn and Moonrise Towers. Several companions and major quest rewards expire if you advance the Moonrise Towers storyline too quickly.

Last Light Inn pivots: Defending Isobel when Marcus attacks the inn is the single most consequential event in Act 2 — if Isobel dies or is taken, the Inn falls, the surrounding area loses its protection, and Jaheira becomes hostile or is killed. She cannot join your party without surviving that fight. Rolan also rushes out to face shadows near the Inn shortly after this — help him immediately or he dies and his siblings' rescue quest in Moonrise Towers loses its conclusion.

Minthara: Only available if she was knocked unconscious (not killed) in Act 1. Find her in the Moonrise Towers Prison alongside the Tiefling prisoners. Rescue her before assaulting the rooftop.

Gauntlet of Shar: Shadowheart's choice at the Nightsong at the end of the Gauntlet defines her entire Act 3 arc and ending. The Dark Justiciar armour inside the Shadowfell is only obtainable during this quest — it cannot be bought or looted elsewhere.

Lift the Shadow Curse: Halsin enters the Shadowfell to retrieve Thaniel as a prerequisite to fully lifting the curse. This quest must be completed before you leave for Act 3. If you advance to Moonrise Towers rooftop without doing it, the questline becomes inaccessible.

04Act 3 — Baldur's Gate City

Act 3 has the most missables because the city contains two hard deadlines tied to boss kills — killing Gortash or Orin locks out several quests and NPCs permanently.

Stop the Presses: The most time-sensitive quest in Act 3. After speaking with the editor-in-chief at Baldur's Mouth Gazette about the smear campaign, you have one long rest to complete the quest. If you kill Gortash first, the quest disappears entirely, meaning you permanently miss key story information and the associated items.

Iron Throne order: The Steel Watch Foundry and the Iron Throne Prison must be done in the right order. If you destroy the Foundry first, the Steel Watchers active at the Iron Throne will massacre the Gondian prisoners and Duke Ravengard before you can rescue them. Always rescue the Iron Throne prisoners first, then destroy the Foundry.

Minsc: Only recruitable if Jaheira survived Act 2 and is in your party when you encounter him in the Counting House sewers. Minsc then joins permanently after a battle. If Jaheira died in Act 2, this entire questline is closed.

Companion personal quests: Astarion's Cazador questline and Shadowheart's House of Grief quest (finding her parents) must both be completed before the final assault on the Netherbrain. After you commit to the endgame, unfinished companion quests are permanently abandoned.

Legendary items: Several best-in-slot weapons are easy to miss — Markoheshkir is in the lower level of Ramazith's Tower (not the upper floor where the fight happens), Nyrulna requires winning the jackpot on the Djinni Ring at the Circus of the Last Days, and Balduran's Giantslayer requires completing the Wyrmway dragon trials beneath Wyrm's Rock.
