Amateur's File

Taken all the way down to base materials, one Amateur's File is 2 crafting steps deep and needs 2 intermediates — Bronze Ingot ×2 and Leather ×1 — which resolve to 3 distinct raw materials totalling 7 units, plus 5 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 507 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 3 are burned by the intermediates, so the real crystal cost is 3 Fire Shard and 2 Earth Shard.

The chain crosses two disciplines — Blacksmith to Lv 2 and Leatherworker to Lv 1 — so no single class can finish it unaided.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Bronze Ingot has the widest use: 76 recipes call for it, spanning six of the eight crafting classes.
