Skin

Within the context of Guild Wars, and CGI in general, the term "skin" refers to a set of textures. The term "skin" is also used colloquially to refer collectively to both a texture and the model it's attached to. The term "reskin" is generally only used to refer to something which shares a model with something else, but has a different texture, such as the Ivory Bow and Shadow Bow, the Fiery Dragon Sword and Icy Dragon Sword, or Elementalist Krytan armor and Elementalist Elite Stormforged armor.
