Reverse and Timeless equips require either 10 dark or black crystals, depending on the equip. Reverse equips require 20% less time pieces, but Timeless equips still require 1 or 3 time rocks. You also need some level 100~120 item crystals, and some stuff you can buy from an NPC on the Profession Map.
As for what drops the recipes, dunno.
