As you progress through Tower of Fantasy, you will come across different Ruins. These are the game's dungeons, which provide a good challenge for those who wish to go through them. Your effort will be paid with a good amount of loot and a relic. But what happens if you want to replay them?
Can Ruins be replayed?
The short answer to the quest is yes. You may replay Ruins that you have completed previously, but there is a caveat to it: Once you have completed one of the dungeons on a difficulty, you may not return to it on easy. This means that if you try, you will not encounter any enemies.
The only reason you should exit a dungeon you've already completed is if you accidentally left a chest or two behind and need to come back to get it. This also means that you'll need to replay the game when you've reached a certain level.
When you return to a dungeon you have completed, it will show you which difficulties you haven't completed yet, and you can select the difficulty you wish to play it on. If you aren't a high enough level to enter the dungeon, it will prevent you from entering until you meet the required level.
