Starting Location: The Thunderstone
To start this quest, speak with Kona who is located in the village of Grund.
Get a thunderstone
Kona wants your help obtaining a thunderstone, which has various mystical properties about it. The suggested method is to challenge Thomlin of Horschan to a fight in which you will win it as the wager. It is possible to steal it from him too, though Kona doesn’t want this to occur as she thinks it will be bad luck.
Defeat Thomlin of Horschan
Head to the nearby village of Horschan where you can speak with him and ask him about the thunderstone.
He doesn’t actually want to give it up. You can try pickpocketing the “thunderstone” from him, but if you remember Kona’s description this isn’t a real one (it doesn’t have a hole in the middle).
To fight Thomlin, you’ll need to either pass one of three Hard speech checks, or if you’ve already completed the task Fight Dirty you can use that as leverage to get him to fight you.
Whichever way you convince him, meet him over near the pen. You’ll also need to pay him 500 Groschen upfront before the fight. Thomlin isn’t too strong, if you’ve already completed Fight Dirty then he shouldn’t give you any more trouble than the other fighters did.
Collect your reward from Thomlin
After the fight, speak with Thomlin again to collect your reward. He’ll confess that he doesn’t have the thunderstone anymore and gives you info on who he thinks stole it from him.
Find out what Peter and Hensel know about the thunderstone
He’ll tell you about Peter and Hensel, who are located in the western town of Raborsch.
Speak to Peter and you will determine that he has also lost the stone, and Hensel is currently being held captive by some pillagers that they wanted to deal with.
Find the military encampment
Peter gives you info about a military encampment nearby where Hensel is being held, and asks you to rescue him if possible. There is a large search area, but it is possible to run into the bands earlier if you have explored, which is located in the building along the stream.
The soldiers will attack you as soon as they spot you, so you can’t try to reason with them to get Hensel out. If you want to try stealthy or just to deal with them more easily, it is recommended to wait until nighttime and you can take out a number of them while they are sleeping. Even if you do accidentally alert them, all the ones that were sleeping will get up and attack you unarmed, making it a pretty easy fight with only 3 – 4 armed soldiers. Make sure to loot the camp after as most of the soldiers have pretty high value items.
Free Hensel
Hensel is located at the back of the camp in the wooden hut. Go behind him to untie him.
Talk to Hensel
After he is untied, speak with Hensel after he runs back to Raborsch.
Ask Mlada about the thunderstone
Hensel doesn’t have the thunderstone either and tells you that it was sold to Mlada in Suchdol. Head there and speak with her.
If you offer to help her husband Peter, this automatically starts the task Primum Nil Nocere. You can also just pickpocket the thunderstone from Mlada if you don’t care about going through the trouble of dealing with Peter, but for completion’s sake, you should finish the task regardless.
Give Kona the thunderstone (Optional) / Return the thunderstone to Thomlin (Optional) / Keep the thunderstone (Optional)
Now that you have obtained the thunderstone, you have three possible options for what to do with it: Give it to Kona, return it to Thomlin, or keep it for yourself.
- If you want to keep it for yourself for some reason, you can tell either Kona or Thomlin that you are keeping it, which will end the quest immediately with no further reward.
- If you return it to Thomlin, you can either take 150 x Groschen or his offer to teach you something that awards Unarmed XP.
- If you give the stone to Kona, you receive some Alchemy XP, a discount at the Grund Horse Trader, and a possible 100 Groschen if you decide to take her money when offered.

Lunaris says
The stone appears to give a +10% buff to stamina regen, +5% to stamina regen for blocks and attacks, and -10% stamina consumption, if I have understood the buff in the xml correctly. So it might be worth keeping.
Dave says
Where did you find this information?
Lunaris says
Game files, I responded to a reddit thread about it as well, went into some detail. But to summarize, in the tables pak file, which you can open with winrar, if you go into the rpg folder, and then open buff.xml, you can search for the thunderstone buff. The params state:
srg*1.1 (srg = stamina regen)
srb*1.05 (srb = stamina regen block)
sra*1.05 (sra = stamina regen attack)
sco*0.9 (sco = stamina consumption)
Those meanings are based on what those abbreviations meant in the first game, which it seems reasonable to assume would be the same in this one.
Side note, I hope you get an alert about this or something Dave, cause the reply button only seems to exist for the parent post.
Yuhu says
Open your “PLAYER” window an choose “BUFFs” and you can see “Thunderstorm Charm”, but it’s not explain the number
Stefan says
Hey, I am doing this quest after finishing the main storyline and I cannot find Mlada as she is not marked on the map, any ideas where to find her?
Gage says
Her house is the southern most one in Suchdol.
Eric says
I’m stuck in the same place. Did you manage to find a solution?
sad says
me too
Grog says
This guide is slightly inaccurate. You can “reason” with the mercenaries. With a (Hard) domination check, you can lie and persuade Andrew to stop pillaging and free Hensel.
Yuhu says
someone in rededit tell, you can give to both of them, by giving one and then steal it back, and then give to another one, and then steal it again for you.
