High Durium Helm of Scouting

Taken all the way down to base materials, one High Durium Helm of Scouting is 3 crafting steps deep and needs 4 intermediates — High Durium Nugget ×2, Ametrine ×1, Dwarven Mythril Nugget ×1 and 1 other — which resolve to 6 distinct raw materials totalling 24 units, plus 54 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 881 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 23 Wind Crystal, 16 Fire Crystal, 8 Ice Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 81, Blacksmith to Lv 81 and Goldsmith to Lv 81 — so no single class can finish it unaided.

All 6 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, Dwarven Mythril Nugget has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
