Gorgruth

Gorgruth is one of the heroes from the death legion, that was created due to a failed experiment by the Wizards of Argnor. When there was an irregularity in Udhin they went to the epicentre, known as Nazgkahan, to experiment with necromancy and later, they united under the leadership of a powerful leader.

It is a very useful hero and for a cost of 3 crystals you have a unit with 3 attack points and 7 defence points. With the Curse 2 ability, it will be nothing but pain for the enemies.
