Grow
In an ancient land, an elf plays a haunting melody on a flute among the trees, growing entire buildings seamlessly from still-living wood. Elsewhere, a fungi malak holds a conversation with the mushrooms of an underground cavern, convincing them to twine together into a latticed armor to defend the cavern against a new threat encroaching from the darkness.
The traditional methods of crafting items tell the story of a crafter retrieving the necessary raw materials and then working those materials via forging, woodworking, tailoring, or other such means; however, this is but one way to create magic items. In places of heightened primal power, such as Amina Dorei, the United Altos Isles, or the fey forests of Arcadia, it might make sense to grow an item from a living thing instead. While most of these examples assume a natural environment, they can just as easily occur in a hidden laboratory, where an alchemist might form magical oozes into specific shapes before curing them with magical reagents, producing a sword as durable as any steel.
Mechanically, the process of growing an item uses the same principles as Crafting it normally, though the details and the story surrounding its creation process differ. However, as this activity has the Rare trait, it is only available in certain circumstances.
