Setting up -
Option "1. Edit" (edit mode) allows party leaders to choose what monsters they and their party will be fighting inside of the dungeon. Currently, players can choose up to 20 rounds of monsters to fight. Players must choose at least 5 rounds of monsters in order to begin the dungeon.

Monsters can be placed in groups of 5, may all be the same kind, and may add up to 20 max. Each monster slot represents one stage of the dungeon. Different monsters cost different amounts of gold. The minimum entrance fee is 5,290 gold and the maximum entrance fee is 1,800,000 gold (1.8 million). When you choose monsters for the slots, the game will automatically also put in a creature one level higher and another two levels higher than the one you chose.

Once the monsters have been chosen by the party leader, he or she will be able to enter the lobby of the dungeon. As soon as the party leader enters the dungeon, the rest of the group will automatically be teleported inside. Inside of the lobby there will be another NPC, and when the whole party gets there you will be allowed to begin the first stage of the dungeon.
The stages -
There are five stages - one for each of the elements: Earth, Wind, Fire, Lighting, and Water. Each stage has its own traps specific to its element. These traps are preceded by a glow. A few seconds after the glow, there will be an attack at each glowing area. The attacks are dependent on the element for that stage. For example, the earth stage will have the attacks be akin to Terra Spear. In each stage, waves of the chosen creatures will spawn for your party to fight against. Once all the creatures have been killed, your party will be allowed to move to the next stage. During the battle, you must work as a team to defeat the waves of creatures while also watching out for the traps. An additional word of advice, just before the traps appear, stop attacking. You have to finish an attack before you can move, so if you’ve just started an attack when the floor starts to glow, you will have a lot less time to run (and will probably be hit by the trap)

The traps come in 5 varieties - one for each element. Every so often, there will be some lighted circles on the floor that will serve as a warning. Make sure to get off of any circle that you all may be standing on because if caught, you will receive 10% of your total health in damage. Anyone can be hit by more than one trap at the same time, So, if you are hit by 4 traps at once, you lose 40% of your health.
