This item is obtained by redeeming the loot card "Ping's Pinning Potion Package" from the Legends of Norrath online card game. Claiming the card grants you a package containing five Potions of Binding. These cards are inserted randomly into booster packs from the Inquisitor set. Also, you receive this card the first time you successfully complete Against the Void, Scenario 1: Prison Break. When you receive the card from the scenario, it may not be traded to other players.
