Riviera Picket Wall

Taken all the way down to base materials, one Riviera Picket Wall is 3 crafting steps deep and needs 4 intermediates — Mortar ×25, Cut Stone ×15, Mahogany Lumber ×10 and 1 other — which resolve to 5 distinct raw materials totalling 175 units, plus 189 crystals.

That bill outweighs 13,549 of the 13,602 recipes tracked here and 2,195 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 44 of those crystals go into the final step; the other 145 are burned by the intermediates, so the real crystal cost is 119 Wind Shard, 50 Water Shard and 20 Fire Shard.

The chain crosses three disciplines — Goldsmith to Lv 45, Carpenter to Lv 39 and Alchemist to Lv 20 — 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
