Find a Cure

	Objectives
1	Explore the Surrounding Area After the Prologue, you'll need to explore the surrounding area to get your bearings and find a lead for a cure. From here, you can explore the Ravaged Beach to pick up Shadowheart and Astarion and Roadside Cliffs for Gale to add them in your party.

After wiping out the Goblins with Wyll, you gain access to the Druid Grove and a lead that the healer Nettie may be able to help you with a cure.

Along the way, you'll meet several important characters, find new companions to join your party, and uncover a sinister plot centering around infected True Souls and the mysterious entity known as the Absolute.

Act 2 Walkthrough

Infiltrate Moonrise Towers

	Infiltrate Moonrise Towers Objectives
1	Head to the Last Light Inn After entering the Shadow-Cursed Lands through either the Underdark or the Mountain Pass, you must immediately find a way to seek constant protection from the Shadow Curse. From here, you can make it to the Moonrise Towers by seeking out Kar'niss's Moonlatern. But the Last Light Inn mainly provides one way to get protection from the Shadow Curse through saving Isobel. ► Seek Protection from the Shadow Curse ► How to Get to the Moonrise Towers ► How to Beat Kar'niss
2	Seek Protection from the Shadow Curse Making it to the Last Light Inn, you meet Jaheira, a leader of the Harpers situated in the Shadow-Cursed Lands, and Isobel, a Servant of Selune and the person responsible for creating the shield that protects the inn from the Shadow Curse. Isobel will be able to provide you some protection from the Shadow Curse if you save her. If not, you must find another way through finding a Moonlantern. More answers are to be found by infiltrating the Moonrise Towers, so you must make your way there after wrapping up business at the inn. Note: Halsin has a quest tied to the Last Light Inn if you have him in your camp by saving the Emerald Grove. Make sure to find Art Cullagh in the inn for lifting the Shadow Curse. ► Seek Protection from the Shadow Curse ► How to Lift the Shadow Curse ► Help He Who Was ► Find Zeflor ► Rescue Wulbren ► Rescue the Tieflings
3	Find Ketheric Thorm's Relic You infiltrate the Moonrise Towers by making it past the darkest areas of the Shadow Curse and presenting yourself as a True Soul to the Ketheric Thorm and the towers' inhabitants. You hear of Balthazar, Ketheric's right-hand necromancer who is tasked with finding a relic (the 'Nightsong') which is the key to Ketheric's immortality. Find this relic in the Gauntlet of Shar to progress the main story. If you sided with Minthara and she is alive after defeating the Emerald Grove, she can be potentially recruited to your party (when saving her from the Moonrise Towers prison) Note: Entering Shadowfell where the Nightsong resides is a point of no return. Make sure to wrap up all of your quests in the Shadow-Cursed Lands and previous areas. ► Gauntlet of Shar ► How to Solve the Silent Library Puzzle ► Find the Nightsong ► How to Kill Yurgir ► How to Beat Gerringothe Thorm ► How to Beat Malus Thorm ► How to Beat Thisobald Thorm ► How to Beat Balthazar
4	Defeat Ketheric Thorm You have found the relic sought by Ketheric Thorm: the Nightsong, and have made the decision of either saving or killing it to make Ketheric mortal. You are now on your way to assault the Moonrise Towers and put an end to Ketheric's reign. Completing this objective will reveal more about the Mind Flayers, and will point the player to Baldur's Gate. Leaving the Shadow-Cursed Lands through the road to Baldur's Gate is another point of no return. ► How to Beat Ketheric Thorm ► How to Solve the Necrotic Laboratory

After learning more about a potential cure and the increasing presence of Mind Flayer Parasites leading to the Moonrise Towers, you make your way to the Shadow-Cursed Lands via the Underdark or the Mountain Pass.

Infiltrate Moonrise Towers covers the beginning of the Shadow-Cursed Lands, from making it to the Last Light Inn up to taking down Ketheric Thorm. It is here that you meet new potential allies, a large amount of fiends and undead monstrosities, as well as learn how to navigate around the dangerous Shadow Curse affliction.
Act 2: Infiltrate Moonrise Towers

Help Your Protector

	Help Your Protector Objectives
1	Reach the Portal At the end of Act 2, players will be assaulted by the voice of the Absolute. However, due to your Dream Visitor getting overwhelmed by Githyanki, the Astral Prism barely helps in quelling the call of the Absolute. Fend off the Githyanki ambushers and enter the portal to the Astral Prism within 3 turns before the Absolute commands you to undergo ceremorphosis. Note: Failing to enter the portal within 3 turns will result in the Absolute dominating your mind. This allows it to command you to undergo ceremorphosis, resulting in a Game Over screen.
2	Go to the Skull Inside the Astral Prism, fight your way to the skull-like structure at the center. Defeat the Githyanki standing in your way and aid the Dream Visitor at the skull.
3	Help Your Dream Visitor Confront your Dream Visitor to reveal their true identity. Then, help them fend off Orpheus' Honor Guard to preserve the protection that keeps the Absolute from dominating your mind. Note: Killing your Dream Visitor will result in a Game Over screen. It is not possible to kill the Dream Visitor and continue the game as normal.
4	Speak to Your Dream Visitor With the day won, speak to your Dream Visitor to receive the Astral-Touched Tadpole. This unlocks partial ceremorphosis, giving tadpole players more powers to work with as they enter Act 3. Note: Opening your mind or consuming the tadpole will change the appearance of your character. As of Patch 1, you will get both a blackened visage as well as rotting teeth if you undergo partial transformation. ► List of All Illithid Powers

The end of Act 2 will finally allow you to meet your Dream Visitor, face-to-face. During your time on the road to Baldur's Gate, you will be assaulted by the command of the Absolute which triggers the protection of the Astral Prism.

However, due to your Dream Visitor getting overrun by Githyanki inside the prism, it is up to you to help them in order to prevent your protection from the Absolute from going out. Fail, and you risk a Game Over.
