Obtain 5 Nether Ray Stingers for Boots at Area 52 in the Netherstorm.
So, I'm just missing the one ingredient that'll give my concoction that little extra kick that it needs.
The sting of the nether rays, roaming around near the shaleskin flayers, delivers quite a punch. Bring me some of their stingers and I'll extract the venom right out of them!
I'm certain the results will be explosive!
