Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks the book of dead quest

Nedd help with finding the book of dead (quest from Igor ).
I killed Barnabus but i cant find the book. There is one closed chest but i cant find a key to open it.

I coudnt find a beer for bandit camp guardian in qquest where two of the bandits wanted to escape. Quest is bo longer active but out of curiosity where could i find it?

There are 3 portals inside his cave. The book is in one of them
And beer could be bought from the innkeeper in the black boar.

Thanks a lot, somehow i missed third teleport

2 You can mindread the drunk on top of the lookout. He hid some in the bushes you can find.
