This quest is a great soloable writ. The snake mobs are mostly two to three down arrows depending on how many are linked. There are lots of harvest nodes to keep you occupied while you are waiting for the next pop. A group of snakes pop across the road to the S between the road leading to the Mythical Forest and the road leading to the shore. A group of snakes will pop on the road to the N leading to the Vallon Mine. Beware of the Luggers who path the road. This writ was soloable in about 45 minutes.
Do Not touch the water in Spirit Lake, a number of water elementals will spawn.
