Guild Wars Description
"No inherent effect. Many Pirate skills, especially spells which find treasures and physical loot from the environment and enemies, become more effective with higher Treasure Hunting."
General Description
Treasure Hunting is a very important attribute for Pirates. This attribute is the reason that Pirates are the best at finding treaure in the most unlikely of places. It is linked to a large number of skills that disrupt the environment to the player's own financial ends. Treasure chests which spawn locked are no issue for a Pirate who has a high Treasure Hunting attribute count.
