Flawless Battle-Stone

Source
Players will have a very small chance to obtain a general purpose Flawless Battle-stone after winning a match against wild pets; defeating higher level opponents increases the chances of obtaining a stone. These valuable items are not soulbound, and can be sold on the Auction House.

Flawless Battle-Stones have a chance to drop from Mist of Pandaria level Raid Loot-bags and Pet Care Packages.
