Loong's Pearl is a new ascension item added in the recent Wuthering Waves 1.1 update that appears on a new island. However, it can only be found in a very niche area.

This item is required for many of the upcoming 1.1 banner characters, so it's important to know where to collect it during the daily reset so you can collect as many as possible when leveling up your characters.

You can find Loong's Pearl ascension materials in Loong's Rest, an area on the new Mt. Firmament map added in the Wuthering Waves 1.1 update.

You can find it in two locations. There is a group of eight around the Resonance Beacon by the lake and many more in the underground tunnel systems beneath Loong's Rest and Loong's Crest.
