CookApps announced that its idle RPG, Fortress Saga, will hold its first collaboration with the popular Japanese IP, The Mage of Water Element. This marks the first time the The Mage of Water Element IP has featured in a video game collaboration.

During the collaboration period, players can obtain all four legendary collaboration heroes for free simply by logging in for seven days. Additionally, a large-scale challenge event themed around The Mage of Water Element will be held.

Collaboration-exclusive dungeons, summoning content, shops, and exchange centers will be opened sequentially. Rewards for the challenge event include collaboration-limited skins, fortress skins, collaboration home buffs, the four The Mage of Water Element heroes, exclusive weapons, and legendary random runes.

A CookApps representative stated, "This project was prepared with a focus on harmonizing the IP with the game's world." They added, "As this is the first game collaboration for the IP, we have put a lot of effort into ensuring it provides a special experience for both fans of the original work and existing players."

The Fortress Saga and The Mage of Water Element collaboration event will run for one month, from February 12 to March 12. Further details can be found on the Fortress Saga official website and community channels.
