Troll of Vergen is a secondary character in The Witcher 2: Assassins of Kings. He can be found in the troll lair in the ravines outside Vergen during Chapter II where is enjoying a bit of elf and onion soup.
He is also the husband of the She-troll of Vergen.
On Iorveth's path, in order to find Triss Merigold who has been kidnapped by the Kingslayer, Geralt must speak with the Troll of Vergen. The creature explains that he did find the sorceress after she fell from the sky. She was wounded and he tried to help her, but his jealous wife didn't appreciate the intruder, so she ran away leaving her husband. Geralt can choose to help the He-troll to find his woman and convince her to go back home. If he accepts, he finds the She-troll on a mountain in the southern area of Vergen, being attacked by Adam Pangratt and a group of his mercenaries. Geralt can decide to side with these men and kill the troll, or defend her and fight the mercenaries.
Note that there are 3 trolls on Iorveth's path that you need to leave be in order to get the Friend of Trolls achievement. If you take the Roche path, you will find 4 trolls, in addition to the three, there's another one hiding in a little cul de sac close to the brothel tent near the Kaedwani camp. His murder is not needed to get the Trollslayer achievement.
- A troll kidnapping a beautiful sorceress? I could believe that. A troll abandoned by his wife for that reason? That's ballad material. Yet not many people would believe a ballad in which a troll asks a witcher for help.
- If Geralt chooses to kill him during Chapter II - Where is Triss Merigold?:
- Discussions between monsters and witchers almost always end the same way. This time was no exception and the troll departed this world.
- If Geralt chooses to help him during Chapter II - Where is Triss Merigold?:
- In order to obtain the Friend of Trolls achievement, Geralt has to choose to help him and tell him that his wife is fine. Telling him that his wife may have run into soldiers doesn't seem to unlock the achievement.
- In order to obtain the Trollslayer achievement, Geralt has to kill him.
