When gathering, there is always a chance of getting an uncommon material instead of getting the raw material corresponding to the node. For example, a player mining from a Krymetal node and get Verdigris Flake instead of Krymetal Ore. These uncommon materials are used to create unguents in Alchemy. They must not be confused with the actual item. For example, it is impossible to refine Pure Verdra Fibers into Verdracloth; to do that, the player would need the normal Verdra Fibers. Take special note of this, especially when purchasing raw materials from other players.
The following is a list of all uncommon materials and the kind of node that they come from.
