High Durium Greatsword

Taken all the way down to base materials, one High Durium Greatsword is 2 crafting steps deep and needs 4 intermediates — High Durium Ingot ×3, Gaja Leather ×1, Pewter Ingot ×1 and 1 other — which resolve to 8 distinct raw materials totalling 33 units, plus 62 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,266 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 47 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 15 Earth Crystal, 8 Wind Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 82, Goldsmith to Lv 82, Leatherworker to Lv 81 and Alchemist to Lv 75 — so no single class can finish it unaided.

5 of the 8 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Gaja Leather has the widest use: 79 recipes call for it, spanning seven of the eight crafting classes.
