Act II, Kaedwen Part VI -- Assisting Dethmold

Act II, Kaedwen Part VI -- Assisting Dethmold

Head to the marker where you will find Dethmold inside the tent with the bodies -- he explains what he has planned -- you are going to go inside the dead assassins mind and relive the events leading up to the assassination attempt, but to do that you need a special poition called Gadwall, which you do not have.

Outside of the tent is a merchant named Master Myron who will sell you the diagram for the potion for 111 Oren, but to make it you are going to need some special ingredients -- these are x1 Aether (Drowner Brain), x1 Caelum (Byronia or Green Mold), x1 Rebis (Celandine or Green Mold), x1 Sol (Verbana), and x1 Vermilion (Byronia or Woldsbane) -- you should have everything since these are all common  ingredients...  This guy actually has other diagrams you may want to own so check his inventory while you are there to get Gadwall, right?  I ended up buying all the Formulas I did not already have so cool :)  Once you have made the potion, save, then take the potion, then talk to Dethmold and tell him that you are ready to go!

Sneaking through the camp to unlock the Necromancer Achievement 

-- Entering the Dead Assassin's Brain --

Once you are inside the dreamlike state you have to recreate their actions...  So first listen to what they say to each other, and then do the following:

Part I: Follow the assassins path, killing the Harpies and soldiers you encounter and getting to the hideout;

Part II: Inside the hideout beware of traps as you make your way to a meeting with Letho;

Part III: Sneak through the camp without being detected;

This process is a bit disjointed, for instance you do not have to get through the gate ahead you just need to move from one side of the zone to the other without being seen which is easy enough if you go behind the tents.  You flash to different areas, and then have the big battle in which Geralt kills you and you unlock the Achievement "Necromancer" (50 G) Relive all of Aucke's memories in Dethmold's vision.

Bearing in mind that you learn some damning information in the process -- like the danger that Triss is in and the secret that Sile has been keeping from you...  You also learn the location of Letho's hideout!  Tell Dethmold all and then quickly head for the hideout, where you discover that Sile has beaten you to it and tried very hard to kill the Kingslayer Assassin to prevent him from ratting her out...

The entrance to the ravines that you want to run to is the one that is directly across from the first sizable water spot in the cliff wall as if you were heading towards the beach where you fought the Wraiths...  There are Gargoyle's and a Golem in the caves -- and the traps, remember the traps -- after you kill the Golem talk to the still-living assassin (Sile sucks at killing people) and you will get a flashback of the Wild Hunt!  It seems that this Kingslayer knew you as well, and what he tells you fills in a memory.

After the flashback you return to the here and now to find that the Witcher Assassin is dead.  Searching his body yields a note -- evidently his name is Serrit, and according to the note he is having serious doubts about his outlook on life and his profession (if you read between the lines). 

The quest now advances and you need to head back and speak with Dethmold, and when you do you finally receive the last artifact that you need to put an end to the specter invasion!  Nice one!

You should level up and the quest The Eternal Battle advances.  Earlier following the vision you will have advanced both Returning Memories and The Assassins of Kings, so bonus!  You may as well apply the Talent Point you just obtained now, while you are thinking about it.

Talk to Dethmold and tell him that you are ready to lift the curse to progress to the next stage...
