"She might not look like Angelina Jolie, but Grendel's Mother brings a beauty of her own to the battlefield: pure, unadulterated devastation. With a slow-speed nuke and a curse that clings like a bad reputation, she challenges the current fast-meta with raw power and tankiness. Discover if this matriarch of monsters deserves a spot on your roster or if she is better left in the depths."
