Shooting across the grass like racing cars, the Grass Snakes are the fastest of the snakes, and have a very poisonous bite. These monsters are found in some of the high areas of Hurnscald, and are hard to reach for the inexperienced (for good reason as they are a high level snake). To get to these snakes, one must head north from Hurnscald and enter the Northern mine. If you take the first left, you will encounter two caves which lead out to open paddocks and fields with these snakes.
They can also be found on the way to the Graveyard, just south of Dimond's Cove, and into the Western fields, before Asphodel Moor, and also within the Graveyard itself.
Once in the mine, take the first left past the Snakes that are in that narrow passage, and take either exit.
