Top 15 Extremely Difficult Bosses in Elden Ring

3. Placidusax

This secret boss is one of the toughest in the game, period. On the one hand, Placidusax towering form is intimidating, their AOE attacks supremely dangerous, and their ability to teleport around the lightning struck arena befuddling, but on the other the battle against Placidisax is an incredible spectacle. A two-headed, ancient beast, a crumbling arena showered in lightning. Seek out this challenge and it’s equal parts difficult and awe-inspiring.
