Reydurran Divide drop menu is archived here, ready for your perusal.
Items did not sell out instantly, although an all-red Glyan did swiftly sell out first. Other items sold down quickly, but most of the 24 new items were still available 30 minutes later. Two hours later, 15 of the 24 new items are still available so there's quite a bit to be had if you missed the drop's launch.
All three colors of Swing Joints are still in stock, so if you were looking to get those it's not (necessarily) too late!
