15 Most Toughest Bosses In The Dark Souls Series

1. Fume Knight – Dark Souls 2: Iron King DLC

The Fume Knight is our choice for toughest Dark Souls boss and for good reason. First off, if you don’t destroy the Ashen Idols outside of Fume Knight’s arena, he just won’t die. His consistently high damage and fast speed makes stamina management tough. With large combo chains, similar looking attacks that make predicting him tough, a powerful AOE attack, strong resistance to magic, two types of damage and becoming faster as time wears on, it’s no wonder that Fume Knight was defeating players 93 percent of the time (as per From Software when the DLC released).
