Roric Wyrmbane enters Teleria as the September 2021 Fragment Collector Event Reward. As a Spirit Single Target nuker, Roric looks to bring his hammer down on his foes, crushing skulls and Stunning them as he goes.
As with all Single Target nukers, they generally lack the ability to cycle around and provide as much impact as AoE nukers however what is unique about Roric is that he will counterattack with his huge A3 (that ignores 50% defense and cannot be blocked by Block Active Skills debuff). This makes him a prime candidate for Retaliation or Avenging artifact sets. He can also provide crowd control and TM on a single target that can mitigate some of the issues with him being a single target.
His passive effects and Aura make him helpful to your team and to improve his damage potential. On paper, he looks like he will use but not on the level of Brogni.
