Confront the source of the spider infestation in Luigi's Mansion: Dark Moon's Gloomy Manor Mission A-6. Defeat the Giant Spider boss and retrieve the Dark Moon fragment.

Walkthrough
  1. 1
    Take the elevator from 2F to the Cellar, which is marked on your map. E. Gadd provides the key to the elevator.
  2. 2
    In the Lobby, you can investigate nearby objects for around 80 Gold, but E. Gadd restricts you to the main lobby until you proceed.
  3. 3
    Upon arriving in the Cellar, use the Dark-Light on the painting to the west to reveal money.
  4. 4
    Go down the slide. Southeast of the bottom, suck up dirt piles to find gold in boxes and a chest.
  5. 5
    Enter the main area north of the slide and defeat the spiders. Vacuum upwards on the east side of the room to collect about 13 Gold. More gold is located behind the knight to the northwest.
  6. 6
    In the north-central part of the room, grab the bulbous thing from the web and drag it back.
  7. 7
    BOSS: Giant Spider
  8. 8
    As you drag the capsule back, a giant spider will attack. It attacks if you get too close, rearing up and attacking with its front legs while dropping two smaller spiders.
  9. 9
    Charge your Strobulb (a device that emits a flash of light). Walk towards the boss while holding X. When it rears up and its eyes open, use the Strobulb to blind it.
  10. 10
    The spider will fall, leaving you time to grab the bulb it was guarding.
  11. 11
    As you drag the bulb back, the boss will hurl poisonous liquid that can stop your progress. Dodge to the side or jump to avoid it. Stay to the right to avoid a knight on the left that will attack with its weapon. Once south of the knight, get close to light up the web you are dragging.
  12. 12
    The boss will shrivel and die, releasing its ghost. Dodge the ghost's tackle attack. After it misses, stun it and suck it up partially.
  13. 13
    Repeat the previous phase, but first, light up the web on the fan in the stone room by spinning the fan with your vacuum and backing off so a knight's flaming torch lights it. This should release a knight to the northeast.
  14. 14
    As you drag the web this time, angle towards the newly-freed knight. The knight will impale the web. Relight the fan's web and spin it to light the impaled web. Defeat the ghost similarly to before.
  15. 15
    For the third phase, go to the end of the path. Stun the spider and grab the loose web ball nearby (not the main web). Bring it to the torch-wielding knight. Light the web, which can now kill spiders that cross your path.
  16. 16
    Approach the second fallen pillar and angle left on its north side to light up another knight's torch. Discard the web ball, grab the main web, and light it with the new torch. This time, you can defeat the ghost.
  17. 17
    After the battle, collect the Dark Moon fragment.
  18. 18
    E. Gadd will call, explaining the captured ghost could possess other organisms, and takes you back to the Bunker.
Tips
  • Before the spider boss fight, it's recommended to sit your 3DS down and hold Up on the Circle Pad to utilize the gyro sensor effectively.
  • Suck up posters and use the Dark-Light on what's beneath to reveal hidden fires.
  • If you haven't collected all 47 webs, you can return to collect them before E. Gadd calls you back.
  • The Cellar is marked on your map after E. Gadd provides the elevator key.
  • The boss's poisonous liquid attack can be dodged by side-stepping or jumping.
  • The ghost boss has infinite health but can be stunned after missing an attack.
  • In the third phase of the boss fight, the web ball you light can kill spiders that obstruct your path.
