You'll collect grims first on this map, so until you collect both don't worry about tomes.

There are 12 collectible shields before the Well of Dreams. The other 8 Collectible shields in the Well of Dreams room. 3 of them will have a rune drawn on them. Punch them into the books. Order doesn't matter.

Quick tip: Avoid watchlights and don't prematurely hit the bells to avoid patrol spawns.

Right outside the first (not functional) watchlight section. If you go to the right, you'll find a shut gate. The grim is located behind it. To unlock the gate you need to go around and shoot the barrel behind the gate, right across the gap.
The door will be open when the barrel explodes.

Then once there, shoot the beam that suspends the chest. In the chest you'll find the grim.


Right outside the second (functional) watchlight section

But first off, take the right path up the ladder. You need to go this way to activate a lever and clear the way to the second grim.

^ Activate the lever and then go a bit back to find the area near the edge that leads down.


You need to parkour to that ladder. On top of it will be the second grim.

Next to second grim.




At the bridge section





At the third watchlight section. You must collect a key at the tip of a spear and then unlock the chest at the bottom of the statue.

Search for collectible shields. 3 of those shields will reveal a different rune, which you need to match the books pages with. Order doesn't matter.

There are 8 shields in the room. Here's a rough sketch of their locations, easy to find. There's one that i missed previously but it's right next to the destroyed staircase.


Once the party finds 3 shields with symbols, the game will spawn 2 bosses. After they're defeated, punch in the shield symbols into the books.

After which the bomb will fall and reveal the escape route.

Then just go up the path and finish the level.

The Well of Dreams room will have four generators, which are evenly spread from eachother in the room. The pipes from the contraptions next to the books have pipes, which should lead to them. To destroy them, you must kite monsters (rat ogre, stormfiend) to use their melee attacks near it and destroy them. Indicator for them being destroyed is lack of glow on it's surface.
