Availability: Blue, Green and Purple weapons can be crafted or found as drops. Some are available from vendors, please check the specific item’s page for details. For any weapons where there were multiple skins of the same type, I included only the easier to acquire version.

Note: For some skins the only difference is the shape of the blades.

Thank you Katelin, Makidai, Memorial, Kisshoten, Zhukov, Durendal and Kaesora for the screenshots!
