Ruined Dragon Battle

Walkthrough: As you arrive in Ruined Kingdom, the Odyssey Airship will again need to be repaired because of Bowser's destruction, forcing Mario to find some Power Moons in order to fix it. This kingdom is a lot like Cloud Kingdom, really only being a stage for another showdown with a certain Boss. There will be no other forms of enemies, there will be no Purple Coins to find and collect.

Begin by heading up the path in front of you, using Cappy on the sword hilts to pull them out to obtain a few regular Coins. If you head down to the left, you should be able to find a caved in area leading to a ledge that holds another Power Moon. From there, head back to the top of the path. After you do, pull the last big sword from its pedestal to reveal a Spark Pylon. Use this very Pylon to ride your way to the large arena of Ruined Kingdom, the same where you will battle the Lord of Lightning himself, the Ruined Dragon.

As the Ruined Dragon appears, quickly take note of how the ground looks: the purple haze in the only indicator you will need to know exactly where the dragon will strike with its lightning breath. Avoid its lightning strikes, as well as the curved blades the strike will emit in all different directions. After several strikes, the dragon will slam its head straight down onto the arena, creating further waves of lightning that will spread out in all different directions. Quickly and continuously jump to avoid them until the electricity final fades away.

At this very point, you will see several swords embedded in the skull of the dragon. You'll need to pull them off in order to take away the chains that guard his helmet, so quickly hop on his skull and pull out as many as you possibly can. If you are quick enough, you can take off his entire helmet in one go and then ground-pound to cause damage to the beast. If you don't finish it in one attempt, make sure to jump off his head when you see him start to flicker so you don't get shocked. If this happens, simply wait for the next wave of attacks to try to finish off the job. If any Spinies try to block you along the way, use Cappy to sweep them away.

After dealing damage to his head, the Ruined Dragon will retaliate by firing more bolts with all the more rolling blades in order to hurt you. When he eventually slams his head to the ground, more shock waves will appear in this second phase of the battle. The waves will have ripples in them to increase the difficulty in dodging them, but it can still be done with perfectly timed jumps. Do the same as before after this, removing the swords on his head to remove his helmet and land another ground-pound to his head.

In the third and final phase of the showdown, the dragon will begin to breath out a spread of lightning blots in a row, each exploding into more rolling blades that will further attack you. After this, he'll again slam into the ground, creating shock waves with even more intersecting waves. After successfully dodging them, you will have to pull out even more swords from his skull, so many that you might need two attempts at successfully doing it. After removing his helmet this final time, land one more blow to his head to win the battle and another Multi Moon. After you do, repair the Odyssey Airship and head onward to Bowser Kingdom.
