High Steel Longsword

Taken all the way down to base materials, one High Steel Longsword is 3 crafting steps deep and needs 6 intermediates — High Steel Ingot ×2, Gagana Leather ×1, Koppranickel Nugget ×1 and 3 others — which resolve to 10 distinct raw materials totalling 38 units, plus 32 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,430 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 6 Earth Crystal, 6 Wind Crystal and 1 other kind.

The chain crosses five disciplines — Blacksmith to Lv 63, Carpenter to Lv 62, Goldsmith to Lv 61, Leatherworker to Lv 61 and Alchemist to Lv 55 — so no single class can finish it unaided.

6 of the 10 raw materials match a gathering node, none of them timed; the other 4 come from vendors, drops or content this site does not track.

Of the intermediates, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
