The highest tier of metal crafting materials in Guild Wars 2, orichalcum, is a rare and expensive ore used in weapon and armor crafting. Alongside other farms, such as a flax run, selling a stack every day can help to accumulate a small fortune in gold. While they can be found throughout the world, including the rich variety, orichalcum nodes are limited and spawn sporadically across Tyria. However, there are a handful of rich nodes that can be mined once a day and are guaranteed to appear in the same location.
