Pirate Luck

 is a pair of legendary boots, valued by many because of their insanely high lootbonus; the fact that they beat the boots with the second highest lootbonus by 6 percent and have their Ids preset make them the optimal boots for Lootrunning. They can be purchased from the Armour Merchant in Pirate Cove at the cost of 4 Liquid Emeralds, and require that the player has completed the quest Beneath the Depths to wear them.
