Type: Knife
Bonus: Targets bleed and are poisoned. Exceptional damage.
Location: This weapon can be found in Dunwich Borers, on the right side of the map, near Hugo’s Hole. This is a high level area, with numerous mobs, thus be careful. It’s pretty tricky to describe the exact location of the weapon because it’s hidden in an underground pond, and the whole area is radioactive, thus, you have to act fast. We suggest you to watch Kremvh’s Tooth video guide first.
Shem Drowne Sword
Type: Sword
