A Needle is an item used along with thread to create armour out of either leather or dragon leather through the Crafting skill. It can be bought in crafting stores, such as Dommik's Crafting Store in Al Kharid. They can also be bought from Moon Clan Fine Clothes on Lunar Isle.
Needles can be found by searching haystacks , hay bales, or digging in the Digsite, as well as shops and tool stores. This is a reference to the idiom "needle in a haystack", which is defined as: "Something that is difficult or impossible to locate; something impossibly complex or intractable."
Needles are stackable items, presumably because they are small, although normal usage does not require them to be. It is suggested to have more than 1 needle as they can break. If a player uses a needle on a cow, they will get the message: "The cow doesn't want that."
