Once he hits 50% HP, the Nameless King will buff himself with lightning his standard attacks will deal more damage in this phase. If he charges up his weapon with lighting, be ready to roll to the side. This may be a two-sweep manoeuvre, which you can dodge by rolling. When the dragon is on the ground, the King will attack with his spear. He will then follow up with a spear crash, which you can dodge by rolling under the Storm Rider. To dodge it, roll aside as soon as it leaves the King’s hand. As the Rider flies around, the King will charge up a Lightning Spear. The Nameless King will also attack from the back of his mount during this phase. Regardless, staying under the dragon’s neck is usually a safe spot, but be prepared for some camera issues.
You can attack his legs throughout the fight, but this will do minimal damage – aim for the head. The fire is easy to dodge if you sprint in the same direction, but you should take the opportunity to dash in from the side and smash the back of his head a few times. When the Rider is preparing to breathe on the ground, the Nameless King will lean forward, and the Rider will hop away from you a short distance. When he does it from the air, you have to sprint away to escape the high-damaging flames. This dragon breathes deadly fire both on the ground and while flying. The Nameless King starts the fight atop his mount, the Storm Rider.
