Hingan Awning (Kura-zukuri)

Taken all the way down to base materials, one Hingan Awning (Kura-zukuri) is 3 crafting steps deep and needs 5 intermediates — Tama-hagane Ingot ×4, Cut Stone ×3, High Steel Ingot ×3 and 2 others — which resolve to 6 distinct raw materials totalling 72 units, plus 72 crystals.

That bill outweighs 13,341 of the 13,602 recipes tracked here and 1,412 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 63 are burned by the intermediates, so the real crystal cost is 54 Fire Crystal, 9 Wind Shard, 5 Ice Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 66, Blacksmith to Lv 66 and Goldsmith to Lv 30 — 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
