Lucky Hand is an essence gem which results in players receiving more silver from defeated enemies. It can purchased after players resolve the quest The Slave Traders, with the seller determined by the quest's outcome — if players exonerated Scholar Songtao, he will sell it to them in the Scholar's Garden, whereas if they exonerated Chandler Ling, he will sell it to them in the Golden Way.
In-game description: "When properly prepared, this gem plucks the silken strands of fate, gently placing small amounts of local currency in the pockets of the people within a certain distance of the wielder. Used in more innocent times to subtly bolster the wealth of the poor, these gems have fallen into misuse, and pickpockets now use it to pad the pouches of those from whom they steal."
