Worldspan Fern

Worldspan Ferns are one of three Weekly Boss materials dropped by the Guardian of Apep's Oasis. This boss is found in the The Realm of Beginnings Domain. Reference the image below for its location:

Worldspan Ferns are awarded by challenging Memories: "They" Too Were Once Flawless on level II or higher. The recommended party level for this challenge is 70+. If this is one of the first three weekly boss domains you have challenged, collecting the rewards will cost 30 Resin. If you have already completed three weekly boss domains, the cost to collect materials is raised to 60 Resin. You can fight this boss as many times as you would like, but will only be able to collect materials one time per week. We recommend challenging it at the highest level you can to obtain the most rewards. Weekly Boss rewards reset every Monday at 4:00 AM server time.

A fern taken from the oasis within Apep's body. At the dawn of time, the world belonged to the dragons. There, the ferns were the first to sprout in the lush verdant world of Apep's court. In the ages after, these ferns would become trees, vines, roots, and leaves, blanketing the world with their touch. But Apep still remembers the first frond as it stretched freely toward the sky, making a sound so delicate as to go unheard.
