¶ Atlas Defense
Every weekend the portals to Atlas Defense is opened. To be able to enter this group event, you will have to find the Wanderer.
Then you can enter the portal. Inside you will find a version of Atlantis Harbour. Goal is to kill all 25 mob waves.
You can choose between easy, middle and hard mode. But only in hard mode there will be a chest after the 25th wave with 25 Atlas Scrolls. Also there is a chance of Gashas inside the chest.
Then go back to the Wanderer to buy items from his shop for Atlas Scrolls.
¶ The Wanderer
To be able to enter Atlas Defense, you need the motivation of the Wanderer. This is a small NPC which changes its position every 2 hours. You can find him either by checking the banner or ask other players. Once you have found him, you need to talk to him and get his Motivation Buff. This buff lasts 12 hours.
Once you are done with Atlas Defense, you need to find the Wanderer again. This time to exchange your scrolls. You can buy various things from him like Gashas, Runes or Titles.
