As I read on various information, in order to build your legendary weapon you will need 2 crafting materials...a list I found on the net for the disciplines needed is :
Axe: Jeweler, Weaponsmith
Dagger: Cook, Weaponsmith
Greatsword: Armorsmith, Weaponsmith
Hammer: Jeweler, Weaponsmith
Mace: Armorsmith, Weaponsmith
Shield: Armorsmith, Weaponsmith
Sword: Artificer, Weaponsmith
Spear: Leatherworker, Weaponsmith
Longbow: Leatherworker, Huntsman
Shortbow: Jeweler, Huntsman
Rifle: Tailor, Huntsman
Pistol: Armorsmith, Huntsman (Some people say it uses Tailor instead of Armorsmith)
Torch: Unknown, Huntmsan
Warhorn: Leatherworker, Huntmsan
Speargun: Cook, Huntsman
Focus: Jeweler, Artificer
Scepter: Armorsmith, Artificer
Staff: Cook, Artificer
Trident: Leatherworker, Artificer
The question is, are this materials tradeable? If not, are account wide at least?Or you need to have those Crafting Disciplines yourself in order to make your legendary? I know it is too early for me to think about legendary weapon, but since the crafting Disciplines are not very easy to level , I want to plan which Discipline my char will have or if I need to level more than 2 Disciplines on a specific character.
