Boss Strategy: The Nameless King is widely considered one of the hardest bosses in Dark Souls III. The fight has two phases. In phase one, you fight the King of the Storm (his mount). Focus on attacking the King of the Storm's head after its attacks. Lightning damage is effective. In phase two, you fight the Nameless King himself. He is incredibly fast and hits extremely hard with lightning-infused attacks. Learn his combos, dodge through his attacks, and punish his recovery. He is weak to Fire.
Rewards: Soul of the Nameless King, 80000 Souls
