Ram your Shield into the ground, throwing up a wall of earth. Enemies can attack your wall segments, and your Slams, Warcries, and Shield Charge will instantly shatter them all. The segments explode when shattered, damaging enemies in front of and around them.
Raise a pair of electrified pylons in front of you which project a wall of electricity between them, damaging and Electrocuting enemies caught between them. Projectiles you fire through the wall become energised, and discharge that energy on Hit as Chaining Lightning beams.
