There is very little doubt that making Bracelets of Arul Saba is one of the most difficult tradeskill operations currently in game because its huge number of processes, vast quantities of materials, and high-ish skill requirements. That being said, these bracers are also one of items considered essential for most characters, even after two expansions have been released since the advent of the Shadowlands. The classic game brought about very few bracer items with very little effects, but the release of the Shadowlands introduced this tradeskill process to make a bracer item that gave a huge bonus to damage.
