Deepgold File

Taken all the way down to base materials, one Deepgold File is 3 crafting steps deep and needs 3 intermediates — Deepgold Nugget ×2, Bright Linen Cloth ×1 and Bright Linen Yarn ×3 — which resolve to 3 distinct raw materials totalling 14 units, plus 29 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 699 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 18 Fire Crystal, 6 Lightning Crystal and 5 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 71 and Weaver to Lv 71 — so no single class can finish it unaided.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Deepgold Nugget has the widest use: 55 recipes call for it, spanning six of the eight crafting classes.
