In order to rapidly develop one's strength in the Return of Dawn, many resources are very critical, and the Ether Core is the most crucial resource within the Ether System. Today, I will go into detail about how to use the Ether Core in Return of Dawn. Since the entire Ether System is part of the game's later gameplay, many new players do not understand how to use it. After reading the following introduction, you will have a clear understanding.

The Ether Core is an important resource within the Ether System, which is unlocked after the 5th phase of the Strongest Trainer ends and the airship level reaches 30. At this point, the Ether Core can come into play. Its purpose is to upgrade the Ether Level of certain buildings, serving as a significant enhancement method. During the Ether upgrade, five stages need to be completed; only after all stages are finished can the building's Ether Level be increased by one. The process consumes Ether Cores, and if canceled midway, only half of the cores will be refunded.

Ether Cores can also be used to upgrade Kulu Trees. After each Kulu Tree is upgraded with Ether, the corresponding Kulus at that level can receive significant attribute enhancements. After upgrading all three Kulu Trees, the Kulus can obtain full attribute enhancements. When all three Kulu Trees reach Ether Level 1, additional new skills can be unlocked. Subsequent upgrades require that the Ether Levels of the three Kulu Trees be consistent before they can be further improved, so it's important to balance their development.

So, how can such an important resource be obtained? First, by purchasing monthly and weekly cards, the rewards from these cards now include Ether Cores, providing a stable way to acquire them. You can also complete tasks in the Adventure Manual, as the tasks there offer core rewards, and simply following the manual can make it easy to accomplish and accumulate over time. Additionally, completing daily tasks or Darkened Investigations can yield Ether Cores once the airship level reaches 30. As long as you consistently complete these tasks every day, you can quickly build up your supply.

The above content is my answer today to the question of how to use the Ether Core in Return of Dawn. After reading this, everyone should have a clear understanding of how to apply this resource and its specific acquisition methods. As a feature of the game's later stages, it's very beneficial for everyone to learn about it in advance.
