MapleStory/Dimensional Crack

There is a crack in the dimension in Ludibrium. Let's investigate it!
 * Required level: 120 or higher
 * Recommended level: 120-139

To enter the PQ, you must use the Dimensional Mirror to enter Spiegelmann's Guest Home. You will find the PQ NPC here; a red stop-sign. You need a party of 3 to 6 to enter the PQ. However, this PQ can be soloed in case of disconnections because you can get Platform Puppet from Sgt. Anderson in the 5th stage (don't exit though!), and each puppet put on a platform represent 1 person.

Requirement

 * 3-6 players in a party
 * Level 120 or higher (Recommended level: 120-139)
 * Max 5 entries daily
 * 20 minutes time limit (Average time needed: 3-5 minutes)

Stage 1

 * Enemies: Ratz from Another Dimension, Black Ratz from Another Dimension
 * Completion: All monsters within the map must be killed, and all 20 Passes must be looted.

Kill, kill, and more kill. The monsters are spread all around the map, from the bottom to top. All the Ratz must be killed, and the party has to collect the passes they drop. Once all the monsters have been killed, enter the portal near the Red Balloon to advance to the next stage.

Achievement Ratio: 10%

Stage 2

 * Enemies: Dark Eye from Another Dimension, Shadow Eye from Another Dimension
 * Completion: All 14 Monsters Killed.

In Stage 4 there are 5 different rooms. Every room contains 3 shadow monsters, except room 4 which has 2. Rooms 1-3 feature Shadow Eye from Another Dimension. Rooms 4 and 5 feature Dark Eye from Another Dimension. Pick your door and tell PQ members you are already in the door so they don't come in yours. Another way instead of telling PQ members is to drop 10 mesos in front of the door to tell them there is already someone in the selected door. The rooms are completely dark, and only the enemies' eyes are visible. Once all the monsters are killed, enter the portal near the Lime Balloons to continue.

Achievement Ratio: 15%

Stage 3

 * Enemies: None
 * Etc: Numbered Boxes
 * Completion: Reach the portal on top.


 * This map contains many boxes in sets of 3 with the numbers 1 through 3 written on each box. Standing on the correct box and pressing UP will teleport you to the next set. Other boxes will teleport you back to the bottom. Guess and check helps, and the combination changes. Reach the top, and enter the portal. Only one person has to reach the top, and then the entire party will be warped next to the portal.
 * A good way to complete this stage, if you have 3 people, is to have each person press up on all the unsolved 1s, one on the unsolved 2s, and the last on the unsolved 3s so that people don't end up being sent to the bottom on the same box, and to prevent confusion.

Achievement Ratio: 10%

Stage 4

 * Enemies: Rombot From Another Dimension
 * Completion: All 4 Rombots Killed.

Kill all 4 Rombots within the map. Two are found on the bottom and two are on the top. After killing them all, talk to the Sky-Blue Balloon to continue.

Achievement Ratio: 15%

Stage 5

 * Enemies: None
 * Etc.: Numbered Boxes
 * Completion: Standing on correct answer of the question

The leader must click on the balloon to start. The balloon will give your party a math problem, and 3 people have to stand on the numbers in the answer (i.e. if the answer to the math problem is 325, 3 people have to stand on the numbers 3, 2, and 5.) If your party does not have 3 people, you may talk to Sgt. Anderson for a Platform Puppet which can be used in place of a person.

Achievement Ratio: 15%

Stage 6 (A Crack on the Wall)

 * PQ Boss: Alishar
 * Summoned By Alishar: Chronos, Platoon Chronos, Master Chronos
 * Completion: Defeat Alishar

This is the final stage of the PQ. Alishar will spawn. Based on his health, the boss will spawn different types of Chronos. Near 75% HP he will spawn regular Chronos, at 50% HP he will spawn either Chronos or Platoon Chronos, and at 25% HP he will spawn Master Chronos along with Platoon and regular Chronos. While fighting the boss, characters may be afflicted with Seal (locks your skills) and Blind (reduces your accuracy). Everyone will need either Eyedrops and Holy Water or only All-Cure potions. Mages don't have to worry about losing accuracy so they only need Holy Water, though All-Cure potions work as well. When he dies, talk to the Purple Balloons to exit.

Achievement Ratio: 35%

PQ Exit

 * Time limit: None

When you're ready to leave, click the NPC and he will escort you out.

For every 5 PQs completed, you can go and talk to the Red Sign and receive a pair of Broken Glasses. The stats can vary (base of 1 to all stats) and they come with 3 slots. They are untradeable unless paired with Scissors of Karma.
 * Broken Glasses

Values are before PQ set effects and assumes 100% achievement ratio (EXP is directly proportional to achievement ratio)
 * EXP reward
 * Level 120+: $$1708000 \times 1.025^{Level-120}$$, capped at Level 129.

Monsters
Note: The monster stats listed here are the base stats (before the PQ stats get calculated), and therefore NOT what you should expect when doing this PQ.
