Hello Aincraders! I had an Idea of what would happen after beating the 100th Boss in Aincrad. Aincrad SubWorld After you beat the 100th floor Boss, A Raging sound can be heard from anywhere in Aincrad. Something beneath 1st floor is moving, sounding like an earthquake, but looks like Metalic gears are moving. In the center of the Starting city, a Gigantic Tower Rises, Lifted by Ancient gears, until it reaches the level top and stops. At the bottom of the tower, A gate was revealed. After a few seconds, the gate starts to Open, making a raging sound that spreads all over aincrad. A new player tries to enter the gate, but he gets knocked off by an invisible barrier force. A Game window opens saying : "Only lvl+80 players are allowed to enter.". This is the Aincrad SubWorld. After defeating the 100 floors, a new gate opens, leading to another 100 floors, but this time, going down. The Cities in the Aincrad SubWorld are be Smaller, and more distanced from each other. Only Cities would be safezones, Mob Spawning rates would be increased, and bosses would become much harder. It would be a Dark red place, with a permanent Red-Orange-Black sky, like a path to hell. In this zone you'd get better items, and Boss Drops would be higher. Requirements to enter this zone: 1- Be at least Lvl 80 2 - defeat the 100th floor boss at least 1 time. (Caesar's Idea) The rest would be almost like in normal aincrad. More Suggestions are WELCOME! Cheers, Leo EDITED at 22/01/2015 - adding @Caesar 's idea.
