Walkthrough (Continued)

King Boo (100 HP)


This first phase is not bad. King Boo will follow you around, trying to corral you into the spike balls on the floor. However, you can turn the tables on him! After the initial spike balls are gone, new spike balls will fall from the ceiling. You can position King Boo by getting him to follow you underneath one of these falling spike balls. Once he's positioned correctly, simply look at him so that he'll stop moving. Wait for the spike ball to land on him, and then you can vacuum King Boo! Use electrical shocks to deal massive damage. Try to avoid the spike balls as you vacuum up the Boo. Repeat the above steps until you whittle away all of his 100 HP.

This second phase is a mansion run. You must try to avoid the obstacles King Boo has set in the mansion as he rolls after you with his body. If he catches up to you, you lose 20 HP but you earn a short reprieve. Hence, it's okay to get hit a few times. There are also hearts and golden bars throughout the run. However, there isn't much guidance I can give you considering this is a run. Simply use your reflexes and common sense--avoid snow, obstacles, and down escalators. Look for hearts and gold. That's really all I can say.

The previous two phases will now repeat with increasing difficulty. The next square brawl will be harder as King Boo will use Boo Dashes and the spike balls now fall quicker. The mansion run now occurs in the dark and there are more obstacles. Try to grab all of the HP hearts in the crawl and try to minimize stupid HP losses in the square brawl. As for King Boo's lightning strikes, watch for the glowing tiles before it strikes. Again, it's mostly repeating the same strategy just with slight increased difficulty. Also, red electrical shocks are your saviors.

The final phase is the square brawl with the same general strategy as before. However, King Boo will now use lightning strikes on nearly the entire arena with only one small square of safety. Furthermore, King Boo will tend to avoid the spike balls near the beginning of the phase. This tends to die down as time progresses, though. Keep chipping away and you should win eventually!


Final Reward: King Boo Crown Piece

What is it with the end of Nintendo games that make me cry a little on the inside? Though, nothing will ever top the first time I finished The Thousand-Year Door. Nothing. But I digress~ Congratulations on completing Luigi's Mansion Dark Moon!


Q: What do the gold versions of all of the ghosts have in common?

A: As for the regular ghosts--spiders, mousers, and bats--, they will drop gold bars when stunned.

Q: I can't move while I'm holding onto something with the Poltergust. What gives!?

A: Let go of the "R" button. While you're holding "R," you cannot pivot; letting go of the "R" button will allow you to maneuver whilst still holding the object.

Q: I can't seem to find XYZ gem!

A: Follow the Walkthrough. Unfortunately, you have to be on the right level for some of the games, meaning you cannot just pick up any old Gem on any old level. A good example of this is the Gem in the Entrance of Gloomy Manor--it can only be picked up during A-3.

Q: The Scar--

A: I don't plan on addressing the Scarescraper as there is another guide that covers this exact subject.

Q: Ghosts keep on hitting me as I'm capturing another ghost! Is there any way to deal with this?

A: Actually--yes. Press "B" as your vacuuming a ghost to do a small leap-dodge. While this dodge isn't foolproof, it can be helpful against certain ghosts. If you absolutely cannot lose HP, simply release your suction and move before you get hit. It's not the fastest solution, but it practically ensures your safety.

Appendix A: Ghosts

Welcome to Appendix A where we're all about ghosts! This section's all about your primary adversaries, so that's why it's first in the long list of Appendices. Remember that I only try to inform you of pertinent information, so don't expect random facts about the ghosts or anything to that effect.

The table below is your directory before the in-depth information. Each ghost has its name listed which is linked to the ghost's in-depth information. The ghost's HP is listed next along with its element and weaknesses. These are the most pertinent highlights. The ghost's locations are also listed out, and those locations are linked to their respective sections in the Walkthrough.

 Coming Soon!

Appendix B: Poltergust Upgrades

This is the COMPLETE list of all upgrades. Poltergust upgrades allow you increase the damage done by your electrical shocks if you charge your suction up more--Level 2 deals 20 points of damage and Level 3 deals 50 points of damage. The Darklight upgrades allow you to shine the Darklight longer without it burning through Luigi's skin. Finally, the Poltergust upgrade makes it much easier to trigger electrical shocks by increasing ghost resistance sensitivity. Each of these upgrades requires gold--each mission's gold is added to the running total. If you need to grind for gold, I recommend the latter levels as they can net you 2000+ gold if you really grab everything. B-2 is a good early choice otherwise. Anyway, here is the table:

Gold RequiredUpgrade
2000Level 2 Poltergust
4000Level 2 Darklight
7000Level 3 Poltergust
10000Level 3 Darklight
20000Super Poltergust

Appendix C: Gem Locations

While I do cover the Gems in the guide, this section will detail where the Gems are located--it's a good starting place if you're missing a particular Gem. The Gems in each mansion are named after some sort of precious metal, so I will call them as such here. Otherwise, they're simply "gems." In the tables below, I abbreviate the cardinal directions to their initials: N = North, S = South, E = East, and W = West. My descriptions are terse mostly because you can look where they are in the Walkthrough if you're having that much trouble pinning them down. I try to place clarifying notes--commonly when a specific level if the area is accessible in more than level but the Gem is not--when necessary. The tables are broken up by mansion/precious metal type:

Appendix D: Boo Locations

One Boo is located in each of the main missions; hence, there are twenty-three Boos spread over the twenty-three missions--even the missions before you can find the Darklight. Some Boo locations are obvious--E-2 comes to mind--while other Boo locations are very much out-of-the-way--D-3. Hence, this section is dedicated to telling you where the Boos actually are. Boo-catching is actually pretty easy in this game because they don't change rooms like in the original. Hence, while battles can take two or three minutes in an unlucky situation, they aren't going to take ten minutes as you work your way upstairs and downstairs, tracking down Boos. Your basic idea is to use your Darklight to find the Boo; he will leave behind shadows, allowing you to better pinpoint him. Use your Darklight to make him appear, then grab his tongue and send him flying. Try to make him bounce as much as possible by sending him in the shorter dimension of the room. The more bounces the Boo makes, the more damage the Boo takes. If you can't get him one shot, run after his last spot and use your Darklight to identify him right after he goes into invisible-mode. Like I said, Boo battles are extremely easy. Here are the Boo locations:
