VIDEO & TEXT GUIDEOnce you reach Novigrad north of Velen if you go to the notice board in Hierarch Square there you will get a contract called Doors Slamming Shut, this is actually the Ashes to Ashes contract.
The suggested level for this is 24
If you follow the instructions on the video you will see there is a building just next to where you got the quest where you will need to talk to the quest giver. Unlike some contracts where you may have killed the beast before receiving the quest you can't do that with this one as you need a key to the house that is believed to be haunted. So make sure to go talk to him first.
Once you have spoken to him you are quicker to use fast travel if you have unlocked places near to the haunted house, if not it really is not that far on horse back to be honest.
Once there use your witcher senses and loot some books as it gives some info on the house, once you have investigated and looted the ground floor head down the stairs and you will see a red pulse from the wall, smash it open with your sword and then the AARD sign, then loot the other room if you wish before heading through, if you get stuck use the video provided.
Once through and across the bridge use your senses and you will learn from reading the book it is an Earth Elemental you will be fighting so for the battle its self i strongly suggest using the QUEN sign and dodging and rolling, he will do a slam attack which you will need to watch out for. If you have the ELEMENTA Oil use that on your sword before progressing because once in the fight you wont be able to. A bomb to use is the Dimerthitum Bomb so make sure you equip that or the enhanced version if you have it. Also pick your favourite Decoction, which ever you find suits your fighting style or you can use the Earth Elemental Decoction which will help with the slam attack your foe will use which takes off a lot of your health.
2 good potions to have equipped are Swallow and Thunderbolt or the enhanced versions.
If you don't have any of these items maybe you should wait a bit until you have some especially if you are on the harder levels.
Once you have sorted your oils, bombs etc jump off the bridge to the right side of the way you entered, the left looking back from where you found the journal and swim over and climb on to the platform and pull the switch, this will open the wall doors that stopped you passing a moment ago so swim back under the bridge and round the side and you can climb back up. Make sure by now you have applied your oils etc because when you go through remember while in battle you can't do this.
When you enter the room run to the back and use the AARD sign on the stand and this will open the shield and if you have not equipped your bombs etc by now too late so if you are on the harder levels be careful. Put it this way i was level 35 and he managed to take off half my health with one hit!
Once you have killed him pick up his loot and return to the inn where you spoke to the quest giver to turn in and then you will get your trophy.
As stated if you get stuck with anything check out the video provided
