Vergen Besieged is the final main quest of the second Witcher 2 Assassins of Kings Enhanced Edition chapter, if you played the game with Iorveth by your side.
Vergen Besieged follows the events that occurred in The Eternal Battle, after Philippa wakes you up, and tells you what happened.
Since this is the final main-quest in the second act, make sure you equip your best weapons and armor, and spend all your talent points.
“Geralt awoke in Philippa Eilharts quarters right in time. Henselts forces were approaching Vergen to besiege the town. There were precious few heroes who could tilt the battle in Saskias favor around, so the witcher had no other choice but to get out of the bed and take matters in your own hands.
Zoltan Chivay awaited him at the gate.”
When to start
After The Eternal Battle
The first goal of the side-quest is clear. You have to meet Zoltan in the southern area of Vergen, where the marketplace is located, near Mahakam gate.
Talk to him and get ready, because Henselt men approach the city. After a short cutscene, follow the stairs to the right, and up on the wall, you will have to fight your way and reach the dwarven mechanism.
Combat Tip: While playing Vergen Besieged you will encounter waves of enemies, and the strategy you should use is based on how you developed your character.
The Yrden Sign is almost every time the perfect choice, allowing you to stun shielded enemies and hit them from behind. During this phase, you can also push your enemies off the wall with your Aard Sign.
As you advance toward the end of the wall, fighting the Kaedweni knights, keep your eyes on the right side of the wall and look for a large wheel, which allows you to spill burning oil on the attackers. After you complete the first objective, return to the gate, and you will be forced to retreat.
Note: Dont fight the army that enters the town. Stay close to Zoltan and follow him.
Continue to follow Zoltan through the city and eventually you will reach the central area of Vergen.
Fight the knights that climb on the walls and make sure that all red dots on your minimap disappear. Then you will talk to Saskia who wants you to check the tunnel that leads to Vergen. Take her with you and she will show you the way.
At this point you will have to kill the mercenaries inside the tunnels until you find Dethmold. The fight against the priest is not an easy one, and you cant win; however, Saskia can. First, take out the soldiers surrounding Dethmold, then try to stun him with your Aard Sign so you can hit him with your sword.
After you manage to injure him enough, he will cast a spell on you, but Saskia will save you using her greatest secret. Talk to her when the cutscene ends, then exit the tunnels and talk to Zoltan.
Note: If you spared the she-troll while playing Where is Triss Merigold?, then you will find out that they joined the fight and they helped you.
Next, you will watch a cutscene showing Saskia who tries to encourage her soldiers and you will fight against a new group of knights. As you try to protect the walls, Iorveth and his elves appear on another wall. Watch the cutscene and follow Zoltan. Descend the wall using the ladder located on the left side, then push forward to reach Iorveth.
After a short dialogue with him, you will have to accompany Zoltan who has to close the Mahakam Gate and trap Henselt inside the city. The lever is located on top of the wall and you wont encounter any enemies.
When the gate is finally closed, Henselt will surrender and a new conversation will start. You will also see Dethmolds swift execution, and how Philippa negotiates with Henselt. But why her?
The answer to this question is given when you follow her and Saskia, helped by Iorveth. When you enter Philippas house, look in the backroom for a book named Poison and Venom.
Your discussion with Iorveth confirms your fears. Philippa subjugated Saskias mind and now they left towards Loc Muinne.
Exit the house and follow the stairs down, where Zoltan and Dandelion await you. Tell them everything you know. Together with Iorveth you leave Vergen towards a new destination: Loc Muinne.
The Assassins of Kings quest updates again, and the third Witcher 2 Assassins of Kings Enhanced Edition chapter begins.
