KCD2 Thunderstone is a long Kuttenberg side quest that starts with Kona in Grund. The shortest reliable route is to expose Thomlin's fake, question Peter in Raborsch, rescue Hensel, and heal Mlada's husband in Suchdol. The optional Two Dead Trees cache is near Hensel's prison camp, but it does not contain the real KCD2 Thunderstone.
Best choice: Give the KCD2 Thunderstone to Kona for the broadest reward bundle. Keep it if its permanent stamina bonuses matter more than a recipe, XP, a horse discount, and Groschen. Complete the Suchdol stage before Oratores, because late-story changes can remove the NPCs you need.
KCD2 Thunderstone Quest at a Glance
| Step | Location | What to do |
|---|---|---|
| Start | Grund | Speak to Kona; Innkeeper Grosch can reveal her marker |
| Fake stone | Horschan | Inspect Thomlin's stone or beat him in a wagered fight |
| Missing stone | Raborsch | Question Peter about Hensel and Andrew Ramhead |
| Rescue | Camp northeast of Raborsch | Free Hensel and speak to him after his escape |
| Optional cache | Two Dead Trees east of Raborsch | Find the pot behind the ram skull below the trees |
| Real stone | Southern Suchdol | Complete Primum Nil Nocere for Mlada |
| Final choice | Grund or Horschan | Give away or keep the KCD2 Thunderstone |
The KCD2 Thunderstone route crosses western Kuttenberg. Carry Saviour Schnapps for the dialogue, rescue, and treatment checks.
How to Start KCD2 Thunderstone
Go to Grund after reaching the Kuttenberg chapter. Ask Innkeeper Grosch for local news to reveal Kona, or find her by the house opposite the tavern. Some guides list Speak of the Devil as a prerequisite while databases allow an earlier start after discovering Grund. If Kona has no KCD2 Thunderstone dialogue, finish that main quest, ask Grosch again, and return. The official patch 1.4 notes also added an alternate quest start by speaking to the priest.
Let Kona explain the KCD2 Thunderstone and ask what a genuine one looks like. The hole through its middle becomes the safest way to expose Thomlin's fake. A Persuasion check reveals more of Kona's motive but is not required to accept the quest.
Finish KCD2 Thunderstone before the point of no return in Oratores; GameSpot's cutoff testing lists it among the quests that fail there. Also avoid starting an active Dragon's Lair quest midway through this route: that separate bone search has time-sensitive behavior and is safer to complete without interruption.

KCD2 Thunderstone: Expose Thomlin's Fake
Ride west to Thomlin Bruthans at the farm in Horschan. The KCD2 Thunderstone route is to inspect his stone and use the dialogue or Scholarship option based on Kona's description. Thomlin admits it lacks the correct hole and points Henry toward Peter and Hensel in Raborsch.
The fight route is optional. Pass Thomlin's hard dialogue check or complete Fight Dirty, bring the 500 Groschen stake, win, and speak to him again. He still cannot hand over the real KCD2 Thunderstone because Peter and Hensel stole it.
Pickpocketing Thomlin only produces the fake stone. It is a clue, not a substitute for the real KCD2 Thunderstone, and it does not complete the search. Use the conversation or fight outcome to unlock the Raborsch lead.
Find Peter and Rescue Hensel
Peter works near the cabbage patch by the first farm at Raborsch's entrance. Say Thomlin sent you. Peter explains that he and Hensel took the KCD2 Thunderstone, attacked Andrew Ramhead's band, and lost. Hensel is now held in the military camp northeast of Raborsch, beside the stream between Raborsch and Bohunowitz.
For the safest KCD2 Thunderstone rescue, save, wait until about 1–2 a.m., wear quiet clothing, and approach from the hill west of the stream. Leave KCD2 Mutt behind because his movement can alert the camp. Hensel is tied inside the rear wooden hut; untie him and withdraw through the grass.
You can instead ask the entrance guard to see Andrew, pass Andrew's difficult dialogue check, or pay a 1,000 Groschen ransom. Fighting also works, but KCD2 Thunderstone never requires clearing the whole camp. After Hensel escapes, follow him or return to Raborsch and speak to him again. That second conversation identifies Mlada in Suchdol and can reveal the optional cache.
If Find the military encampment does not clear, enter the camp center before fighting from range. If Hensel already fled, find him in Raborsch and talk. These are community workarounds, not guaranteed fixes; reload a pre-camp save if the KCD2 Thunderstone journal stays stuck.
KCD2 Two Dead Trees Cache Location
The KCD2 Thunderstone Two Dead Trees marker is east of Raborsch near the lake and Andrew's camp. It is optional and does not hold the KCD2 Thunderstone. You only receive the marker after talking to Hensel again following his rescue.
At the marker, stand below the two bare trees and walk downhill toward the water. Find a ram skull mounted on a stick beside the cliff. The cache is a small pot in the shallow rock alcove directly behind the skull. Loot the Groschen, then continue the KCD2 Thunderstone quest in Suchdol; finding this pot does not advance the main objective.
Get the Real KCD2 Thunderstone from Mlada
Mlada lives at the southern end of Suchdol. She bought the KCD2 Thunderstone for her bedridden husband, Peter, and will only surrender it after Henry helps him. Agreeing begins Primum Nil Nocere. Save before the examination because several checks are one-attempt decisions.
Peter suffers from extreme anxiety rather than a fever or physical injury. Examine every attribute option you can pass, choose the anxiety diagnosis, and give him Chamomile Brew. If Henry has none, buy or brew it before continuing; the KCD2 recipe guide covers potion preparation and the Lethean Water recipe offered later.
Use the additional diet, prayer, and fear-management dialogue options only when Henry's scores support them. Too many failed checks can make Mlada withhold the KCD2 Thunderstone. After treatment, wait for the journal to update—normally at least one full in-game day, sometimes closer to two—then tell Mlada the KCD2 Thunderstone can help someone else. She hands over the genuine item.
KCD2 Thunderstone Best Choice and Rewards
Kona gives the broadest standard rewards; Thomlin offers cash or training; keeping KCD2 Thunderstone retains the only lasting combat benefit.
| Choice | Reward | Best for |
|---|---|---|
| Give KCD2 Thunderstone to Kona | Alchemy XP, Lethean Water recipe, Grund stud-farm discount, optional 100 Groschen, paid Craftsmanship training | Broadest reward bundle and Kona's intended outcome |
| Return KCD2 Thunderstone to Thomlin | 150 Groschen or an Unarmed XP lesson | Cash or fistfighting progress |
| Keep KCD2 Thunderstone | Thunderstone Charm while the real item stays in inventory; preserve later quest uses | Stamina builds, collectors, and players planning later shortcuts |
Kona's discount matters only if you still plan to buy in Grund; compare mounts in the KCD2 horse guide. Lethean Water is available elsewhere. Otherwise, keeping KCD2 Thunderstone is mechanically distinct.
Keeping the real stone preserves two later choices: replace the stolen talismans in Warding Off Evil, or use it to enter the Von Grolle estate in The Fifth Commandment. Save first; surrendering KCD2 Thunderstone can cost its inventory buff.
KCD2 Thunderstone Buff Stats
Current database entries list four hidden effects while the real KCD2 Thunderstone remains in Henry's inventory:
- stamina regeneration: +10%
- attack stamina regeneration: +5%
- block stamina regeneration: +5%
- stamina consumption: -10%
The real KCD2 Thunderstone may show its charm in an unexpected status panel. The fake stone from Thomlin is not a reliable substitute after Henry exposes it. Keep the genuine item in inventory and check the Thunderstone Charm status rather than relying on the object's flavor text.
Some players give away the KCD2 Thunderstone, steal it back, and try to collect multiple rewards. Reports conflict about stolen status, duplicated stones, and persistent effects, so treat that as an exploit. For a clean save, choose Kona for rewards or explicitly keep the KCD2 Thunderstone for the buff.

KCD2 Thunderstone Mistakes to Avoid
- Do not confuse Thomlin's fake with the real KCD2 Thunderstone.
- Ask Kona what the KCD2 Thunderstone looks like before visiting Thomlin.
- Speak to Hensel after the escape; untying him alone may not advance the trail.
- Save before Peter's examination and bring Chamomile Brew.
- Wait for the Primum Nil Nocere update before assuming treatment failed.
- Finish Suchdol before Oratores changes the area.
- Keep the real KCD2 Thunderstone in inventory if you chose its buff.
KCD2 Thunderstone FAQ
Can You Skip the Thomlin Fight?
Yes. Inspect the KCD2 Thunderstone, use Kona's description to expose the fake, and continue to Raborsch. The wagered fight is an alternative route.
Where Is Hensel in KCD2 Thunderstone?
Hensel is in the rear hut of Andrew Ramhead's camp northeast of Raborsch. A quiet night approach is safer than a frontal attack.
Who Should Get the KCD2 Thunderstone?
Give the KCD2 Thunderstone to Kona for the most rewards. Keep it when the permanent stamina bonuses are worth more to your build than her recipe, XP, discount, and Groschen.
Can You Finish KCD2 Thunderstone After the Story?
Not reliably. Suchdol changes late in the story and Mlada can disappear. Complete KCD2 Thunderstone before the Oratores cutoff.
