In mission 31, the night elves need to reach the Barrow Dens of Winterspring Valey to awaken the rest of the druids. This is a mission to test the night elf mobility. Orcs and undead fight from the both sides of the way and there are poor gold mines. With short stops to collect the gold, and avoiding combat with arc and undead, the elves must reach the dens. The druid Furion will help in this mission. He is a ranged attack hero with first spell entanglement. The second spell is very useful. Furion can cast Force of Nature over a portion of trees and the trees will come alive to fight for the druid.
