This is a witcher contract that you can obtain in Novigrad from Kurt Dysart named NPC, who is located on the second floor of the Kingfisher Tavern.
Suggested lvl for this contract is lvl 24 but I completed this when I was only level 20. The name of this quest is *Doors Slamming Shut*
The monster of this contract is an Earth Elemental named Therazane so it's fighting technique is similar due Golem, although this Elemental monster have some some sort *earth shock wave* move that you will see and hopefully dodge.
I did have some good equipment though but at this point of the game when you are going for this quest, you might possibly have some good stuff too to be obtained. I used only Swallow potion and some food, dodged, attacked when I did see an open and occasionally I used Axii sign to slowdown this monster. The fight was not particularly hard but if you will be a too bold and dare devil, you will probably die.
Bestiary of the game says that this *Therazane* creature has only two vulnerabilities: Dimeritium Bomb and Elementa Oil. So if you are going for full prepare for this battle, craft these !
Ok so walkthough of this quest:
1. Talk to Kurt Dysart in The Kingfisher tavern that is located in the Hierarch Square in Novingrad. Accept the contract but you can also haggle the prize like every else witcher contract.
2. Follow the quest objectives and you will come eventually come to Moldavie Residence.
3. Yet again follow the quest objectives, search the house by using you're witcher senses for clues. At the basement of the house, use Aard sign to blast one of the cracked walls and venture forward.
4. You will arrive to a small cave that has a bridge which will lead you to other side of the cave. Other side of this cave has a large door. At the other side of the door you will hear roaring. Search the area around of the door and you will find a journal. Read the journal and you will then realize that it is a Earth Elemental behind that door.
5. Next obviously you will have to find some way to open that door. Just drop down to from the bridge, swim far right of the cave, find and use the switch that is located there. Then swim far left of the cave and jump to platform and you will be again at the same point where the door is. The door is open now and you will see the monster inside of the bubble.
6. Before venturing in SAVE the game just in case. Use Elementa Oil for you're silver sword if have any and equip the Dimentium Bombs too. When you are inside of the room, you will see the monster (but it cannot attack you so dont worry), search with you're witcher senses a support pilar (glowing red object) and blast it with Aard sign. Just before you will blast it however, be ready to fight !
7. Once you have defeated this monster and looted it, return to Kurt in Novingrad to complete this quest. Once you have obtained you're reward and the conversation ends you will acquire the achievement. Congratulations !
