Realm of Murder

The followers of Isha worship life in its many forms. Their faith, long unchecked, has tainted these lands. This will be undone! Their altar must be destroyed, and the temple must be cleansed with the blood of Isha's worshippers! Our lord will then claim the temple for his own! To this end, I will speak of my order, and one of its most closely guarded secrets ... Mixing the blood and venom of ferocious beasts with the leaves of the Lifebane plant will create a draught that produces great fury during battle. Collect the blood of the forest's bears, the venom of its spiders, and leaves of Lifebane! Combine them within this bowl in Khaine's name, and consume the resulting mixture! Let the Lord of Murder's fury consume your soul, then lay waste to the she-god's holy temple!

Search the recesses of Avelorn for the rare Lifebane plant. Slay Treehunter Recluses for their venom. Kill Forest Stalker bears for their blood. Mix the ingredients together in the obsidian bowl Vathin has given you.
