Glade Wall Chimney

Taken all the way down to base materials, one Glade Wall Chimney is 3 crafting steps deep and needs 4 intermediates — Steel Plate ×3, Steel Rivets ×2, Oak Lumber ×1 and 1 other — which resolve to 4 distinct raw materials totalling 30 units, plus 42 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,081 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 22 Fire Shard, 13 Ice Shard, 4 Earth Shard and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 36, Carpenter to Lv 32 and Blacksmith to Lv 29 — so no single class can finish it unaided.

All 4 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
