Search the Cellar Walkthrough


Inside the doctor's basement, there is a hidden lever behind three chests. Pull it to reveal the hidden passage behind the bookshelf. 


To open this mirror, you need to make it believe you are an ally of its master. Tell it you despise Szass Tam (A legendary lich and leader of Red Wizard of Thay), and you seek survival and power. If you give the wrong answer, this mirror will send an exploding construct to destroy you.

Behind this mirror, you find the necromancer's lab, read his note to start the quest. The book is placed on an altar behind a locked door. Be careful when you take it, the door will be locked again and two fireball trap will be activated (pressure sensitive). Lockpick the door and run as soon as you got that book, or put some other object on the panel to deactivate the trap.

Now you will need the Dark Amethyst to open the tome, it can be found in Whispering Depth. There are 2 ways to enter this area. Either by using the well in Blighted Village, or through the basement of the house on the right of the village front gate.


(Break the wall to enter the Whispering Depth.)

You can use your rogue to sneak in and get the Dark Amethyst, or fight your way there. (Be very careful when you explore this area, there's Phase Spider Matriarch near the waypoint. Defeat her and you can get Poisoner's Robe )


Before you open the book (right-click and select to put on Dark Amethyst), save the game for better results. You will need to pass multiple Wisdom checks to finish reading. (Grants exp and Speak with Dead spell)

If you decide to destroy the tome, use spells with radiant damage type. (Guiding Bolt for example)

      "To open this mirror, you need to make it believe you are an ally of its master." in combat I used turn undead and that undead ran through and opened it for me. Until now I didn't even know there was a mirror.

        Choosing to close the book on the third check instead of reading on gives you a better save point if you’re having trouble beating the higher DC check.

          Save scummed for like an hour to get past all 3 checks (DC 10, 15, and 20! Wisdom) thinking that the reward must be worth it. Yeah, Larian really be trolling us with a measly amount of EXP and Speak with Dead... which everybody and their mother already got from that level 1 crypt. Why not something new and actually cool like a limited Animate Dead? Getting a free zombie or skelly minion for people who can't get familiars or animal companions would be sweet.

          God damn it, I am beyond salty.

          Just give unlock the book and feed it to Gale. Literally all it's good for.

            Destroying or giving the book to a companion rewards 50xp, reading it yourself is 50xp if you pass all 3 checks, but only 20 if you fail any of them.
            if you fail the third check you get a PERMENANT debuff called "baleful knowledge", disadvantage on all wis checks and saves.

              How the hell do you get divination to work for the saving throws? I've tried casting it before opening the book and also mid-dialog, but I'm not getting the bonus d4 dice on my wisdom checks.

                I've gotten past the freezing dialog sceen.
                First of, I used a mage hand to throw the book out of the caged room, and actually took the book with me to my camp as well as the amethyst.

                Regardless.. you put the amethyst IN your bag. Then READ the book, you get the cut screen with the dialog. Get to the frozen part, hit space to advance,as mentioned below.
                Now you have the option to interact with the amethyst in the dialog.

                  If the trap is already going when you get to the book, just toss something onto the plate where it normally is. That will stop the traps from firing. If the cinematic cut scene gets stuck, just hit "space" to advance the dialogue.

                    need to keep the undead that spawn from the caskets away from that last casket before the mirror. if they get to that one it starts the trap in the cell with the book.

                      Failing the checks can get you a debuff that permanently reduces your wisdom save throws. Recommend adding “SAVE FIRST” before opening the book in the guide

                        The Quest is very bugged, The tome is not on the stone tablet, but behind it in the spider web. The trap is already going.
                        You can throw something onto the table to disarm the trap and then grab the book but the cutscene is bugged and will just leave you stuck there staring.
                        I guess we will need a patch here.

                          I must have broken this quest. When I walked up to the mirror , the fire trap was already set off (no book) Note did not start the quest either. :(
