Witcher 2 Choices and Consequences

Do NOT read any further unless you've already played the game at least twice, and have taken both paths.
You have been warned.

This list only includes choices where you see the consequences only later in the game, so the many decisions that you make within individual quests, that affect only the current quest, are excluded. Quests where you may expect a later consequence, but there is none, are also included.

Vizima

(choices from the first game that affect the second)

Adda - Kill or Cure

• May affect the endings (only for Roche Path/Rescue Anais)
• Changes dialogues at La Valette, Pontar Valley and Loc Muinne regarding the succession in Temeria

Thaler vs De Wett

If you defended Thaler, you receive a gift from him in Flotsam (NB: This is bugged - you receive the gift with an imported game regardless of your decision)

Order, Scoia'tel or Witcher's Path

• Minor dialogue changes in Vergen
• If you supported the Order, you get easier access to Loc Muinne on your arrival there, don't need to fight the knights after rescuing Anais, have a single meeting with the Order's armourer and a possibility to trade, and have some conversations with Siegfried.
• If you supported the Scoia'tel, you get money from Vivaldi's Bank in Vergen
• An encounter with an Order Knight in the Kaedweni camp has different outcomes depending on the path you took.

La Valette Castle

Your Response to Newboy

The quest Melitele's Heart is available in Flotsam only if you get the talisman from Newboy. To get the talisman, you must either

• Ask for details, then advise the Reavers that the talisman is cursed, or
• Tell them that you're unsure, then, when you meet Newboy after the prison escape, make sure you're seen and loot it from his body after the fight.

Defend the Peasants at La Valette

If you defend them and choose not to ask for any reward, you receive one later in Flotsam from their relatives.

Kill Aryan or persuade him to surrender

• Changes in the gameplay for the Prison Escape - either Aryan, or his mother and Shilard, assist you to leave.
• If Aryan is alive, he sets fire to La Valette Castle as you leave. It's unclear how much damage is done.
• Changes the dialogue with Radovid in Loc Muinne (Roche Path). The precise details of how and why the children left La Valette Castle and what happened to them afterwards is different. However, it's not clear on whether there really is any difference, or if Radovid has been fed false information by the Nilfgaardians.
• If Aryan is alive, you have a conversation with him in Loc Muinne
• Possible impact in future games/expansions, as this is defined as a "major decision". Aryan is known to oppose the Nilfgaardians. His mother feels the same way, but is forced into cutting a deal with them in order to protect her younger children.

Flotsam

Return Iorveth's sword to him, or knock him out

If you give him his sword:

• There is an anti-nonhuman riot in Flotsam on your return.
• The quest for the start of the Iorveth Path is given by Iorveth, and is "Capture the prison barge".
• You have an option to go to the aid of the nonhumans during the riot. If you do so, and take Iorveth Path, you will get a reward later in Vergen.

If you knock him out:

• Roche takes Iorveth prisoner, and Flotsam is celebrating on your return.
• The quest for the start of the Iorveth Path is given by Zoltan, and is "Free Iorveth from the prison barge, and capture the barge".
• The minor quest "Margot's Disappearance" becomes available.

The choice also changes the conversation you have with Iorveth in Vergen if you take the Roche path but opt to go to Iorveth's assistance.

At a Crossroads

Your decision here totally changes the quests for the rest of the storyline in Flotsam, everything in the Pontar Valley (including your location), your entry into Loc Muinne and the Rescue quest, and your allies and companions throughout the game. It also has major impact on the possible endings, and is the most significant choice made in the game. Other consequences are:

• On Iorveth Path, Loredo may live or die, depending on a later decision. On Roche Path, he will always die.
• On Iorveth Path, Dethmold will be executed by Saskia at the end of the Battle for Vergen. On Roche Path, he will live or die, depending on later decisions.
• On Iorveth Path, Philippa will be blinded by Radovid. On Roche path, we hear that he captured her, but have no other information.
• Anais may only be rescued on Roche Path. 
• Saskia may only be cured on Iorveth Path. On Roche Path, you never find out the truth about her identity.
• Your opponent in A Score to Settle will be different, although the outcome will be the same.

The Eternal Battle is the same for both paths, and the Triss rescue is almost the same, except for the start of the quest.

Free the Elven Women or Kill Loredo (Iorveth Path only)

• Changes the gameplay for the rest of the chapter
• Quest reward in Vergen if you free the Elven Women

Vergen (Iorveth Path)

Let the peasants kill Stennis, or insist on a trial

• If he's alive, you have an additional quest when you cross the mist, to get blood from Henselt. If he's dead, you get the blood from his corpse.
• Major decision with impact on the endings

Investigate Baltimore's Disappearance

The "Suspect: Thorak" quest becomes available only if you complete the investigation into Baltimore's disappearance before investigating Stennis.

Kaedweni Camp (Roche Path)

Give the Manuscript to Dethmold, or keep it

If you keep the manuscript, the quest "From a Bygone Era" will be available in Loc Muinne.

Allow Roche to kill Henselt, or talk him out of it

• Changes the dialogue in the rest of the storyline in Vergen.
• Major decision with impact on the endings

Go to Iorveth's assistance, or don't

• No subsequent impact

Loc Muinne

Rescue Anais, Philippa or Triss

• Major decision with impact on the endings, and on Roche or Iorveth's future.
• Rescuing Anais will result in Dethmold's death. Otherwise, he will survive on Roche Path.
• Rescuing Triss will result in Shilard and Renuald's deaths.
• Rescuing Philippa will result in Saskia being cured. Otherwise, she will be either spellbound or dead, depending on your later decision.
• Changes the encounters you have between your return to Loc Muinne after the dragon fight and your meeting with Letho.
• If you don't rescue Triss, Letho will.

Persuade Roche to hand Anais to Natalis, or keep silent (Roche Path, Rescue Anais only)

• Impact on the endings and Roche's future.

Kill Sile or let her escape

• Change the dialogue with Letho, otherwise no impact

Kill the dragon or walk away

• On Iorveth Path, killing Saskia makes the state of the Pontar Valley unclear.
• Changes the dialogue with Iorveth, Roche or Triss on your return to Loc Muinne

Kill Letho or let him live

• No subsequent impact
