Act 3 Baldur's Gate Lower City Recommended Progression

While Act 3 offers a high degree of freedom, it also features a complex structure where the order and completion status of quests can mutually influence each other. The following progression is an example to smoothly advance the story without missing companion quests or important items and equipment. Feel free to adjust the order flexibly according to your situation.

1. Explore the Rivington District: The starting point of Act 3. First, clear the side quests in the southern area. Begin the investigation into the "Open Hand Temple Murders" and at the "Circus of the Last Days," undertake the quest to find the dismembered body of Dribbles the Clown, or challenge Akabi the Djinni to a rigged game. If Astarion is with you, don't forget the event at the "Gur Camp."
2. Proceed to Wyrm's Crossing: Wyrm's Crossing is the bridge connecting Rivington and the Lower City. Attend Enver Gortash's coronation at "Wyrm's Rock Fortress" located here. It's recommended to avoid combat and adopt a cooperative stance. Special dialogue will occur if you bring Wyll or Karlach. Additionally, a crucial deal event with the devil Raphael takes place at "Sharess' Caress."
3. Enter Baldur's Gate Lower City: Once in the city, first secure a resting place at "Elfsong Tavern." Afterward, advance Jaheira's companion quest and recruit the legendary hero Minsc via the "Guildhall." His addition will significantly stabilize your forces.
4. Conclude Companion Quests: Each companion's story reaches its climax. Add the respective companion to your party and head to their destination.
   • Astarion: To "Cazador's Palace," where the vampire lord Cazador awaits.
   • Shadowheart: To the "House of Grief" to resolve her roots and faith.
   • Gale: To "Sorcerous Sundries," which determines his relationship with Mystra and the fate of the Netherese Orb.
   • Jaheira/Minsc: Cooperate with or confront the "Nine-Fingers Guild," which controls the city's underworld.
   • Wyll: Rescue his father, Grand Duke Ravengard.
   • Karlach: Search for Infernal Iron to repair her infernal engine.
5. Advance Main Quests (Orin & Gortash): Once companion quests are settled, it's time for the confrontation with the two Netherstone holders. Before tackling Gortash, the classic route is to neutralize his forces at the "Steel Watch Foundry" and rescue the hostages imprisoned in the "Iron Throne." As for Orin, by investigating the serial murders occurring in the city, the path to the Bhaalist Temple where she lurks will open.
6. To the Final Battle: Once you acquire two Netherstones, the story will enter its final phase. Prepare thoroughly before engaging.

Key Areas: Important Events and Hidden Items/Equipment

The vast Baldur's Gate hides countless secrets. Here, we will highlight particularly important locations and powerful items and equipment you should acquire.

Rivington

A relatively safe area serving as the entrance to Act 3. The focus is on gathering information and small-scale quests.

• Circus of the Last Days: The Djinni Akabi's roulette here is rigged, but if you successfully pickpocket him, you can obtain the magical ring "Djinni's Favour." Equip this ring and challenge the roulette again to outwit Akabi and be sent to another dimension, where you can acquire the legendary trident "Nyrulna."
• Open Hand Temple: Pressing a hidden button in the basement grants access to a secret room. Important clues for the murder investigation can be found here.
• Gur Camp: If you bring Astarion, an event will trigger with vampire hunters targeting him.

Wyrm's Crossing

The gateway to the Lower City, dominated by a towering fortress. Many political events unfold here.

• Sharess' Caress: On the second floor, you'll meet the devil Raphael and be forced to choose whether or not to accept his deal. His proposition is to give you information on the Netherstones in exchange for Orpheus's Hammer. This choice significantly impacts the late game.
• Wyrm's Rock Fortress: There are numerous areas to explore, including Gortash's private chambers and the dungeons. In the underground passage "Wyrmway (Dragon's Lair)," you can uncover secrets about Balduran, the founder of Baldur's Gate. If you defeat the dragon Ansur at the very end, you can obtain the legendary greatsword "Balduran's Giantslayer."

Lower City

The most expansive and complex area in the game, densely packed with main quests, companion quests, and side quests.

• Sorcerous Sundries: Visited during Gale's quest. After a confrontation with the proprietor Lorroakan, you can acquire the legendary Quarterstaff "Markoheshkir" and "Ketheric's Shield" from his collection. The portal to the upper floor can be activated by operating a lever visible with effects like See Invisibility.
• House of Grief: The culmination of Shadowheart's personal quest. A large-scale battle against Shar's followers awaits. Defeating their leader, Mother Superior Viconia, will cause her to drop the legendary shield "Viconia's Walking Fortress."
• Devil's Fee: By speaking with the proprietor Helsik, you can perform a ritual to travel to Raphael's domain, the "House of Hope." If you defeat Raphael at the deepest part of the house, you can obtain the game's strongest heavy armor, the "Helldusk Armour," including a full set of Helldusk equipment, and the legendary hammer "Orpheus's Hammer."
• Sewers: Many secrets are hidden here, including the entrance to the Bhaalist Temple and locations related to Minsc's quest. It is very extensive, so explore while carefully checking your map.

Important Points and Cautions for Progression

Time-Sensitive Quests

Some quests in Act 3 can fail or have their situations change if certain actions are taken. Particular attention should be paid to the "Iron Throne" and the "Steel Watch Foundry."

• Relationship with Gortash: If you don't start the "Iron Throne" quest before becoming hostile with Gortash, all prisoners will die. If you wish to rescue Wyll's father, Grand Duke Ravengard, or Omeluum, you must always go to the Iron Throne before defeating Gortash. Similarly, destroying the Steel Watch Foundry will make you hostile with Gortash.

Orin's Companion Kidnapping Event

After entering the Lower City and progressing some exploration, an event will occur where one of your companions not currently in your party is kidnapped by Orin. There is a priority for kidnapping targets, with Halsin, Lae'zel, Gale, and Minsc being common choices. If a companion has an important quest pending, you can temporarily add them to your party to prevent their abduction. Kidnapped companions cannot be rescued until Orin is defeated.

Summary

The Lower City of Baldur's Gate is truly the culmination of Baldur's Gate 3, an expansive and dense area. Countless choices and stories await players, each leading to the ultimate ending. The progression and points introduced in this article are merely examples; forging your own adventure path is also a core enjoyment of this game.
