Deepgold Helm of Fending

Taken all the way down to base materials, one Deepgold Helm of Fending is 3 crafting steps deep and needs 4 intermediates — Deepgold Nugget ×2, Bright Linen Cloth ×1, Oroshigane Ingot ×1 and 1 other — which resolve to 5 distinct raw materials totalling 19 units, plus 33 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 733 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 6 Ice Crystal, 6 Lightning Crystal and 1 other kind.

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

All 5 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, Oroshigane Ingot has the widest use: 114 recipes call for it, spanning six of the eight crafting classes.
