The Black Riders of Mordor are one of the most versatile heroes in the game. They excel in a lot of different roles if they get the appropriate attention. However, the borders between the roles are often fluent and one role can easily transition into another in a blink of an eye. For instance, a Nazgul who just trampled some infantry might be attacking a resource building the next moment.
Last but not least, Nazgul achieve the Morgul Blade ability at level six, which poisons and cripples an opposing unit for a short duration. If the affected unit dies under the effect of Morgul Blade, it will turn into a Wight. However, this ability is not a role of the Nazgul in itself, but it can still support your Nazgul and army pretty well, as the Wight regenerates health by hitting opposing units. The Morgul Blade also deals quite a bit of damage against heroes.
Hopefully this guide gave you some insight on the Nazgul and how to use these heroes effectively.Discussion Topic
