Whatsoever a Man Soweth… is the final quest of Hearts of Stone. All three of Olgierd’s wishes are fulfilled, and Gaunter O’Dimm comes to collect his soul. Geralt must decide whether to let the pact run its course or bet his own soul to save the man who caused all this.
How to start Whatsoever a Man Soweth…
It begins after Scenes From a Marriage, when you go to meet Olgierd’s man at The Alchemy inn in Oxenfurt. The suggested level is 36 and the quest itself gives 200 XP. The other rewards depend on how it ends.
Gaunter at the inn
O’Dimm is waiting at the inn. He stops time to talk undisturbed and tells Geralt to bring Olgierd to the Temple of Lilvani, killing a drunk who interrupted them before he leaves. Olgierd’s man then mentions that Shani wants to see you.
Professor Shakeslock
Shani is packing to serve as a field medic, but she has found someone who might know about Olgierd’s pact: Professor Shakeslock. She helps Geralt sneak into the Oxenfurt Academy grounds. The blind professor hides in a protective circle and explains how O’Dimm can be beaten: challenge him to a game of wits, with your own soul at stake. Moments later an accident takes the old man’s life.
The temple and the final choice
The temple lies beyond the caves east of Toderas, the same ones used in Contract: Phantom of the Trade Route. Geralt hands Olgierd the rose or the painting, and O’Dimm declares the contract complete. Olgierd insists the deal said they had to meet on the moon, so O’Dimm blows away the dust to reveal a moon mosaic on the floor.
- Let O’Dimm take Olgierd: Olgierd dies and O’Dimm offers Geralt a reward: the Caparison of Lament, the Horn of Plenty, a Bottomless carafe, a pile of crowns, or nothing at all. You can also ask him to find Ciri. He can’t, but before The Isle of Mists he offers advice on getting a better ending with her.
- Challenge O’Dimm: only possible if you visited Shakeslock. Geralt bets both souls on solving O’Dimm’s riddle before time runs out. Win, and Olgierd is free and gives you his sabre, Iris.
Solving O’Dimm’s riddle
The clock starts when you leave the temple, and every point of interest you examine costs extra time. Most of them are decoys. The fastest route:
- Follow the path away from the temple and take the right fork, ignoring the ruins on the left.
- Cross the bridge, take the left path at the next split, go under the bridge, then keep left and then right to a red glowing spot.
- Optional: climb the stairs there and pull the Viper venomous silver sword from the stone. This is the only normal way to get it.
- Head left to the house on the hill, get past the two gargoyles and go inside, then down the stairs.
- O’Dimm smashes the mirrors as you approach. Instead, go to the dry fountain in the courtyard, behind one of the mirrors on the left. Examine the dry steps by the cracked wall and break the wall with Aard. This starts the final cutscene.
Tips
- Don’t skip Shani. Without visiting Shakeslock you can’t challenge O’Dimm at all. It is also your last chance to say goodbye to her.
- This is your only visit to the Academy grounds, so loot what you want there. A shortcut in: jump off the middle of the bridge into the river.
- You can’t save during the riddle and running out of time is a game over. The game does make a checkpoint at the start.
- Have at least half your health before heading down to the mirrors. Quen won’t help there.
- If you never won Shani’s gwent card, it lies on the upstairs table in her clinic after the quest.
