Hidden Act 1 Content#

Major Act 1 Decisions#

1. Save the goblins or the Grove: help the goblins massacre the Grove → Minthara joins the party, evil path / save the Grove → later tiefling story, good path.
2. Hag deal: kill the hag and take the hair, +1 ability / release the hag and keep Mayrina alive.
3. Githyanki: enter the purification pod → requires an ability check and can grant a legendary weapon.
4. Kagha’s secret: investigate Kagha’s room → uncover the Shadow Druid conspiracy → expose her or let her go.

Act 2#

Region Overview#

Shadow-Cursed Lands Survival Guide#

A light source is required throughout the Shadow-Cursed Lands. Without one, you take necrotic damage every turn. Light-source options: Moonlantern, obtained from the spider woman or druids in Act 1; torches, one for each character; or the Light cantrip, available to Clerics and Paladins. The inn’s basement contains a permanent Moonlantern—make sure to take it. Recommended Act 2 order: Last Light Inn, safe point → explore the Shadow-Cursed Lands → scout Moonrise Towers → Gauntlet of Shar, Shadowheart’s quest → assault Moonrise Towers. Light sources: Moon Lantern, from the spider lady or druids in Act 1; Torches; or the Light cantrip. The basement of Last Light Inn has a permanent Moon Lantern—must-pick. Recommended order: Last Light Inn → explore Shadow Lands → scout Moonrise → Gauntlet of Shar → assault Moonrise.

Key Quests#

Major Act 2 Decisions#

1. Shadowheart’s choice: whether to kill the Nightsong—affects Shadowheart’s alignment/class.
2. Isobel survives: if she is captured → everyone at Last Light becomes a zombie.
3. Ketheric: you can skip the first phase of the fight by persuading him to surrender—requires accumulating specific dialogue options.

Fast Travel#

Exploration Tips#

1. Platforming: BG3 has a long jump distance, and many hidden areas require jumping across cliffs.
2. Disarm traps: Rogues/Rangers should keep Perception active throughout exploration because chests often have traps nearby.
3. Knock: level 2 spell that opens locks and saves the Rogue some work.
4. Save before dialogue: save before important conversations because a failed roll can permanently lock you out of content.
5. Speak with Animals: level 1 spell/potion—talking to animals can reveal hidden information and quests.
6. Speak with Dead: level 3 spell/amulet—talk to corpses to obtain clues.
7. Feather Fall uses no prepared slot: level 1 ritual spell that consumes no spell slot—cast it on the entire party before cliff-jumping/falling sequences.
8. Stock Misty Step scrolls: the most useful scroll in the entire game, valuable in both combat and exploration—buy every one you see.

Act Transition Guide#

Act 1 → Act 2#

The Underdark route is strongly recommended—it offers more experience, better equipment, and richer side quests. The Mountain Pass is faster but skips a large amount of content.
