Forcing Back Foliage In The Pits Of Brume

A quick check of your map indicates the Pits of Brume aren’t far away; a short jog through the bog in a roughly southeasterly direction. Along the way, you may encounter another Bandit Camp. This one has around four foes and a dog, and closer to the Pits entrance, a pack of Wild Dogs may cause some minimal panic. On the meadow grass just before you discover the Pits narrow cave entrance, expect an Archespore to need weeding.

Follow the narrow tunnel until it bends round to the left, and take the right (upper) fork at the junction. This way you can overlook the main pit cavern, and deal with two unruly Archespores. After the plant life is cut back, check the far (northwest) end of the pit, where the journal of Witcher Lexandre can be found near a small burlap cot. A vial, and more importantly, the remaining Witcher diagrams are found in the knapsack here.

This concludes the quest for the Grandmaster diagrams, but you still need to leave this pit; simply return the way you came, or head further in to gather any remaining loot you wish.
