Steel File

Taken all the way down to base materials, one Steel File is 2 crafting steps deep and needs 2 intermediates — Steel Ingot ×2 and Toad Leather ×1 — which resolve to 4 distinct raw materials totalling 8 units, plus 13 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 529 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 8 Fire Shard and 5 Earth Shard.

The chain crosses two disciplines — Blacksmith to Lv 34 and Leatherworker to Lv 26 — so no single class can finish it unaided.

3 of the 4 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
