Black Pearl - Item - World of Warcraft
The Black Pearl is used by Enchanters to make the Runed Truesilver Rod. Tidal Striderhave the best drop rate for a Black Pearl. It will be in the Big-Mouth Clams that they drop. Some people stated that they got it on the 18th clam. I got mine on the 28th, I'd expect anywhere between 5-10 minutes of grinding for this item.
