Other

Other
The item page "Other" is used for materials and sellable items. Materials can be found by slaying monsters, completing zone quets, or on gathering spots. They are used for blacksmithing and as requirement for various quests. Make sure to also check out the Material Drop List page, for a listing of materials found in the zones.

Materials
Materials are sub-divided into the grey and violet (rare) category. However, the rarity of the material and therefore how hard it is to find it seems to have no relation to the item icon. The following materials can be found in the game:

Ore
Violet ore can only be found as reward for NPC/Player quests or as drop by killing monsters that spawn during a zone quest event. Red Ore can be found as reward for zone quest events.

Sellable
Sellable items can be found on various gathering spots. They serve no purpose, aside from providing an additional income.
