Garlean Concrete Inner Wall

Taken all the way down to base materials, one Garlean Concrete Inner Wall is 2 crafting steps deep and needs 4 intermediates — Bismuth Ingot ×6, Manganese Ingot ×6, Annite Whetstone ×4 and 1 other — which resolve to 7 distinct raw materials totalling 108 units, plus 172 crystals.

That bill outweighs 13,489 of the 13,602 recipes tracked here and 1,426 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 156 are burned by the intermediates, so the real crystal cost is 96 Fire Crystal, 60 Wind Crystal, 8 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 86, Blacksmith to Lv 86 and Goldsmith to Lv 86 — so no single class can finish it unaided.

All 7 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.
