Spoilers for Idle Champions
Portrait
Jang Sao, a celestial voyager, traveled the Astral Planes for centuries collecting stars and painting galaxies with her cherished companion, Kwin. When Kwin departed, Jang Sao carried on her wishes of painting the cosmos. Now a wonderful artist, she immortalizes the heavens, reality, and most important of all, her friend.
Jang Sao will be a reworked champion in the Feast of the Moon event on 4 November 2026.
Only abilities that have seen some changes will be displayed here - and be aware that there’s a lot of guesswork involved. Some abilities may not have names - some may have the wrong names - or specialisations might not be marked as such - etc.. Focus on the effect data itself.
Please do me a favour and don’t get all melodramatic about what you find here. I - and CNE - don’t appreciate it. These are spoilers and will almost certainly change before release - likely multiple times. That and we don’t have access to any upgrade data prior to release. Making assumptions on how the champions will turn out based on this information would be premature.
The Mysterious Wanderer (Guess)
Jang Sao increases the damage of all Champions in formation slots with 2 or fewer adjacent slots by 400%. This is increased by a further 400% if Jang Sao is in one of those adjacent slots.
