Walkthrough

1. If you are Level 50 or above, head to Cronus City and find Knight Elroy (284,403) on every Monday and Friday to learn about the Ruin Tower.

2. Monsters from Cronus, Elven City, Misty Marsh, Gobi Desert, Dark Marsh, Icyland, Island, and Volcano will drop Devil Crystal Scraps in the wild. Collect the scraps, and combine 5 into a Devil Crystal. Give it to Knight Elroy to enter the Ruin Tower. Or just pay him 88 EPs to enter directly.

3. There are altogether 8 floors. Kill all the monsters on the first floor, then you can go to the next floor.

4. It's getting harder to reach the next floor, but rewards are getting even nicer. Strong bosses are waiting on the 6th, 7th, and 8th floor. Only true heroes can make it to the last floor!

Boss of the 6th floor: Lord Winders
Boss of the 7th floor: Gory Queen
Boss of the 8th floor: Chaos Medusa
