Ok, I just checked and I actually have one of these. It's the only one I have. Can't even guess price. Anyway, here are the stats:
Unrolled
2730.1 dmg
+1429-1709 Poison Dmg
+997 Dex
+30 Max Spirit
+12% Movement
+13% Tempest Rush Dmg
and of course (Tempest Rush gains the effect of the Tailwind rune)
