The Bone Chests are rattling and will open in just a few hours! If you didn't manage to gather one from Sepulchure's forces this past weekend, Cysero still has a few in stock but they will be gone before the boxes open at 5pm tonight.
The Bone Chests have opened! Check in with the Black Market Moglin to upgrade the items found inside. You can combine the items with Vertebral Columns to upgrade them. The Vertebre are located in the Special Essences shop.
