Mercy is Power is a Quest in Divinity: Original Sin II. Finding Windego, the old woman who blew up the ship back in the prologue, you are offered the choice to help her in Arx. Will you do so?



Important NPCs



Mercy is Power Objectives

  • Encounter Windego in the Sallow Man's camp and kill her.
  • Encounter her again in Arx, below the prison.
  • Speak to her.
  • Give her the Swornbreaker weapon to sever her ties with the God-King (optional).



Mercy is Power Walkthrough

Deep inside the Sallow Man's camp, you will find a letter in the war room about Windego, the witch who blew up the ship bringing you to Fort Joy. You will meet her in person once again, this time as a skeleton, and she will attack you. Kill her and cast spirit vision. Talking to her yields no real answers except that she is sworn to the God-King. After the conversation, her spirit will disappear.

You will meet Windego once again, this time in the deep below the Magister's prison at Arx. To get there, you will first need to persuade two Paladins to allow you to pass the locked door and head downstairs. Attempting to teleport past the locked gate will render the guards hostile, if spotted.

Head downstairs and speak to the Loremaster, where you will once again need to pass a speech check or tell them that you were the one who sent a war owl to the Paladins informing them of the Black Ring collusion with the Magisters back in the Blackpits in Act II in order to speak to Windego.

From here, interact with the device nearby and if you removed your source collar with the help of the blacksmith back in Fort Joy, you will be afforded the option to turn off the switch without spending source points. Speak to Windego and she'll tell you that she is no longer the God-King's favorite chosen - Lord Linder Kemm is. She will then leave, intent on aheading to Lord Kemm's estate to obtain his Swornbreaker, but not before giving you a "Charm Voidwoken" skillbook as a reward first.

At this point, if you let her leave without giving her the Swornbreaker and have not freed Arhu yet, you will find her corpse on the upper platform in Arhu's prison area, to the side. Casting Spirit Vision and speaking to her will reveal that her spirit is on the verge of being torn apart by the God-King, and you will have to either consume her source to spare her from that fate (but still damning her all the same), or let the God-King consume her. You can loot her corpse for 2 virtue tokens after; these tokens grant 2 source points each when consumed.

If you stop her before she leaves though, giving her a Swornbreaker to sever her ties with the God-King, she will finally be able to leave for the Hall of Echoes. If you do so, you will be rewarded with a "Charm Voidwoken" skillbook and a choice of Epic-quality loot (level 18). You will still be able to loot her body for 2 virtue tokens if you choose this path.

Either way, the quest is complete, regardless of whether you gave her a Swornbreaker or not. You will receive no XP for finishing the quest.

If you attack her, you can loot her body for the 2 virtue tokens. Killing her grants no XP and also forfeits the skillbook. The quest is complete after she dies.





  • There are 2 Swornbreaker weapons in-game, one forged with the parts found on the Nameless Isle, along with the tablet back in Driftwood, and one inside Lord Kemm's vault. The one forged with parts scales to your level, so if you are intent on using it, it may be wise to wait until a high level before crafting it.
  • If you already looted Kemm's vault including his Swornbreaker before speaking to her, she will still say that she will leave for Kemm's vault to find his Swornbreaker. If you subsequently head back there to meet her, you won't find her there at all. This is considered a good thing, since if you have not looted Kemm's vault before speaking to her and didn't give her the Swornbreaker, she will meet her demise in Arhu's prison.
  • You can give her a depleted Swornbreaker with zero durability after using it.




  • A "Charm Voidwoken" skillbook upon freeing and talking to her in Arx, completing the quest.
  • Additionally, a choice of epic-quality loot (level 18) if you give her a Swornbreaker weapon.

      I have got the quest stuck to Windego's Fate. After freeing her, I have found Windego in the room just before Lord Arhu's prison (the one with the blue mosaic floor, to be clear), alive. I spoke with her, but did nothing and went on to free Lord Arhu. After freeing him, I then went back and she disappeared. I cannot find her anywhere, dead or alive, and the Mercy is Power quest is still active. What's going on? How can I close the quest?

        There is a way her soul won't be called by the God King. So I gave her the Swornbreaker and she killed herself with it, then used spirit vision. Ok now, in order to not give her soul into the God King call a character with the SCHOLAR tag has to talk to her, then a unique dialogue option will appear and her soul will go to the Hall of Echoes instead. I just did this today and that worked for me

          So i give her the scythe, she severs her bond with the god king, thanks me in return. And then i cast source vision and see her spirit standing over her corpse, saying god king is going to claim her and asking from me to get in a tug of war with the god king over her soul. things just dont add up at all with her storyline no matter how i look at it.

            This is bugged, got no exp for giving the Swornbreaker to her but the quest closed. Just got some useless lvl18 epic loot. Her spirit was also still there and eating her source didn't change anything. Just keep the swornbreaker and kill her for the 2 virtue tokens.

              1) She's haf epic loot, not divine 2) After I've casted spirit vision (after she killed herself with swornbreaker) her spirit was still consumed by the God-king.

                  In DE you can head down from the magister's barracks to Reimond's Hideout. From there one of the small upper platforms in the corner has a lever that drops a ladder down. That ladder leads up to a secret room, which connects to the room Windego is being held in. You'll need to move some crates and destroy a torture device (or jump/teleport past it) to reach the Paladins questioning her.

                    I'm playing DE and gave the Swornbreaker from Kemm's vault to her. She then used it on herself and died, but not before thanking me as her last words. After that, the reward menu appeared. I was able to loot her body of the two Virtue Tokens. However, when I cast Spirit Vision, her soul was still beside her body and talking to her revealed that the God King was trying to take her soul. This is extremely odd, considering that she already used the Swornbreaker to sever her ties to the God King. I eventually wrestled with the God King for control and managed to cast her soul to the Void (Windego's preferred choice).

                      Note that if you want to save her don't try to consume her spirit when you meet her in sallow man's cave because her attitude will be -50 when you see her in arx prison and she will be immediately hostile if you don't have points in persuasion (that's how it was it was for me, and there is no option to give her gifts to improve attitude). If you persuasion is high she will talk normally but this will create a weird but, where even if you give her the swornbreaker and the quest closes saying she left for the hall of echoes, if you cast spirit vision she will still be there saying how the god king is trying to get her, as confirmed by other players bellow.

                        I guess this quest can bug out in the DE version. Let her go without giving her Swornbreaker. Went to the vault like the quest suggested. But no where to be found her body/ghost.

                          I literally do not see why you would use "Charm Voidwoken" over "Charm". It literally is just less useful.

                              Gave her swornbreaker upon freeing her and found her later next to a shrine around where Ahru is imprisoned and she had a broken swwornbreaker and 2 virtue tokens on her.

                                Mercy is power, mercy is power... man, with all the times you try to leave people alive only for them to act like child-eating puppy-killers... this game really sends conflicting messages.

                                  I'm unable to approach windego in arx. When i try to, she instantly attacks me, but because she is still in the cage, I cannot retaliate as I cannot select her as a target

                                    You can get the "Charm Voidwoken" skillbook AND KILL the undead ***** for the Source Tokens(Looted of her corpse) if you attack her before the final ending of the conversation. There will also be a battle of wills with the God King when speaking to the Spirit of Windego. Why is this not mentioned?
