This guide will help you get past them all.
Once there,search for Moreau’s grave.It’s the partially opened one near the large tree.
Examine the tombstone to check that it’s correct, then examine the grave.
Geralt will realize that the journal filled with the professor’s work is gone.
But the Witcher doesn’t give up easily, so you’ll need to find the thief.
After that, do the same to the Professor’s body in the grave to get a new objective.
The game will then place a new objective marker on the map.
To get to the place you desire, you’re gonna wanna go swimming.
Unfortunately, multiple creatures will be underwater waiting to attack you.
Several crossbow bolts should put them down for good.
Also, underwateryou’ll see the remains of a large platform that has stairs on both sides.
Swim around to the back of it to find a portal that you must enter.
Mostly you’ll have to follow the path that’s laid out in front of you.
Although, at one point, you’ll come across some spike traps.
After that, you continue making your way through the area until you’re ambushed by some guardians.
They’re two ferocious panthers who’ve just come to life.
At the top, look to your right to see a hole in the floor.
Drop down, and make your way through the cave.
Otherwise, head left and climb over a large stone step.
Pick it up and read it to find out how to unlock a door you’ll shortly encounter.
Afterward, use the boulder in front of you to climb up to the next level.
You’ll then need to fight another panther.
Once again, Quen is your friend here.
To open it, you’ll need to hit the four protruding stones around you with crossbow bolts.
Your next task is to kill the thing.
Dimeritium Bombs and Elementa Oil can significantly help you take the monster down.
The trick is to always go through the portal that the central statue is directly facing.
The place is filled with things to examine, including a megascope.
The other is atop a bench between a cell and all the big machinery.
Place them both into the megascope and watch each entry to learn about the Professor’s experiments.
Afterward, Geralt summarizes that to enhance his abilities, he needsgiant centipedes.(Charming.)
This will lead to a cave containing pale widows.
The simple act of destruction creates a way for you to re-enter the lab.
Then unequip all of your gear and weapons before stepping inside the thing.
When Geralt comes back out, he’ll have access to the Mutation abilities.
To finish the quest, enter the newly-formed portal at the back of the room.
