Top 15 Extremely Difficult Bosses in Elden Ring

5. Mohg

This boss specialises in blood magic, and fully embracing his Omen blood is Mohg, wielding bloodflame magic with extreme ferocity. However, these spells are easily dodged, but should they land they deal colossal damage. Survive those though and once Mogh reveals his wings during his second phase, his speed dramatically increases, and those blood spells become unblockable. Mogh is optional, but seeking out the toughest opponents in Elden Ring is kind of the point, right?
