Shadow Temper = 2 essence of shadows + neriak nectar + elf blood (trivial brew at 135)
This shadow temper is what makes this item rare. Yes the skill involved to make it is a pain in the gozaru to get to, but not too hard (~185+). After camping Shadowed men for the rare drop essence of shadows, and elves for HOURS, the result is 1 or 2 tempers.
Smiths who can make this, usually only make it for themselves, and maybe a friend or two. If you want some cultural armor, get the temper yourself, and you will be much more likely to find your smith to make it for you.
Just a rant about tempers. I myself am trying to make these, and have camped elves for about 6hours for 15 bloods, and shadowed men for about 2hours for only freaking ONE essense of shadows, not even enough for one temper!
