Buying and using Mortal’s Bane Brew

Buy from the Peddler of Wonders

The Peddler of Wonders trades in southwestern Svartrau. Check the current potion stock for Mortal’s Bane Brew; buying the finished drink gives you an option before gathering all four crafting ingredients.

Unlock the Matriarch’s shop

The Matriarch’s shop is in the hidden Uriash village. Follow A Friend Like This into Song of the Mountain, choose the peaceful dialogue with the village elder and follow her to open access to her Witchcraft shop. She lists both Mortal’s Bane Brew and Supernatural’s Bane Brew, so choose the one matching the enemies you are preparing to fight.

Choose the brew for mortal enemies

Keep this brew for fights against mortals. Supernatural’s Bane Brew covers supernatural enemies, while Beast’s Bane Brew covers animals. The shared human-and-vampire use means you choose this drink for the target category rather than the time of day.

Plan ingredients for both brews

The recipe uses one Vial of Human Blood, two Animal Bones, two Wild Boar Kidneys and two Kobold Brains. The Peddler also lists Vial of Human Blood and Wild Boar Kidney among his ingredients, which can help fill part of the shopping list when you already have the recipe.

If you want to craft one mortal brew and one supernatural brew, reserve four Kobold Brains between the two recipes. Their other ingredients differ; the supernatural version uses Tainted Marrow, Kobold Bile and a Psoglav Heart.
