Whatsoever a Man Soweth...

Whatsoever a Man Soweth... is the last quest in the DLC Hearts of Stone''. ''

Meet at the Alchemy Inn
After Geralt retrieves the violet rose, he goes to meet Olgierd at the Alchemy Inn. When he arrives, he finds Gaunter O'dimm instead. As a drunk stands between Geralt and the merchant, O'dimm stops time and Geralt speaks with him. O'dimm tells Geralt that in order to fulfill the remainder of their contract, Geralt has to bring Olgierd to meet with him at the Temple of Lilvani. O'dimm leaves, but not before killing the drunk for interuppting their meeting, and once time starts again, Geralt speaks to one of Olgierd's comerades, which Geralt tells him to inform Olgierd to meet at the temple. The man tells Geralt that Shani wants to see him.

Final Goodbyes
If Geralt chooses to meet with Shani, he finds her preparing to leave for the front lines to help as a medic for the soldiers. Geralt asks her if she found anything about Olgierd, she says she found someone who might know about him, a Professor Premethine Shakeslock.

When they reach the Academy, Shani will convince the guards to allow her inside, and she will help Geralt get into the building. Once Geralt breaks into the residence, the support beams begin to rot. He finds the blind professor in a protective circle. At first, Shakeslock thinks Geralt was sent by O'dimm, but relaxes after Geralt tells him he is a witcher. He asks him about Olgierd, which he tells the story Olgierd sought him out to find out about O'dimm and how to banish the being. Geralt learns that Olgierd wanted to marry Iris, but he needed to be high status to be accepted by her family, so he made a deal with O'dimm. O'dimm agreed to the deal, but at the price of Vlodimir's life, after which his heart went cold and his marriage fell apart.

He tells Geralt that to defeat O'dimm, one must challenge O'dimm to a game of wits, with one's soul at stake. After he tells Geralt, the beams begin to collapses, forcing the professor to slip and break his neck.

After the meet, Geralt can meet Shani for one last goodbye and they leave as friends.

Temple of Lilvani
Geralt meets Olgierd at the temple, where he delivers the violet rose, fulfilling the third wish. O'dimm appears in the moon light and informs Olgierd that he has fulfilled their contract by granting three wishes and meeting on the moon (revealing a moon portrait on the ground beneath them). O'dimm comes to claim Olgierd's soul, and if Geralt did not meet Shakeslock, O'dimm claims the man's soul. If Geralt did meet Shakeslock, he has a chance to stop O'dimm and challenge the fiend for both their souls.

Contract Fulfilled
Should Geralt allow him to take Olgierd's soul, he will allow Geralt to ask for a boon (though Geralt can reject the offer): Once the two finish their business, O'Dimm departs.
 * To be as swift as the wind
 * Never go hungry again
 * A bottle of vodka that's always full
 * Money (5000 Crowns)
 * Geralt can ask him to find Ciri, though O'dimm will say it is beyond his power.He will give Geralt advice on how to save Ciri by:
 * Making Ciri laugh when she's depressed.
 * To allow Ciri to vent her frustration when she is betrayed.
 * When she wants to grieve a friend, that Geralt should grieve with her.
 * When Ciri is scared, Geralt should encourage her, but not act in her stead.
 * For Geralt to never make Ciri feel like he sold her out.

Breaking the Pact
If Geralt challenges O'dimm, O'dimm transports Geralt to another dimension, where he tells the witcher a riddle in how to find him. Geralt travels around the baren land trying to discover the answer the riddle with O'Dimm throwing distractions out for the witcher, including Specters to fight him. Geralt discovers the answer for finding O'Dimm is a mirror, but O'Dimm keeps shattering the mirrors. At the fountain, Geralt discovers water and breaks a dam, revealing a reflection, locating O'Dimm. The beast growls and vanishes into the light, defeated and Olgierd's soul is saved. Returned to the normal world, Geralt meets Olgierd, who has returned to his mortal state and Geralt's mark removed. Olgierd decides to start his life anew, and gives Geralt his family sword, Iris.
