Crafting will be unlocked by recipes or maybe progression in one’s profession
(Recipes seem to be dropped by mobs or bought at a vender. Basic ones might be considered trash loot if already learned)
There does seem to be different levels of rarity in dropped recipes.
Rarity of items follow classic MMORPG classifications.
goes common (gray) -> uncommon (green) -> rare (blue) -> epic (purple) -> legendary (orange)
Basic artifacts seem to be obtained as common crafting recipes. This means most likely rarity of recipes will create artifacts of that rarity.
Looks like mana and health potions are craft-able item
