Riviera Ornate Door

Taken all the way down to base materials, one Riviera Ornate Door is 3 crafting steps deep and needs 5 intermediates — Steel Ingot ×8, Steel Hinge ×4, Clear Glass Lens ×2 and 2 others — which resolve to 6 distinct raw materials totalling 36 units, plus 43 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,369 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 19 Fire Shard, 10 Water Shard, 8 Ice Shard and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 27, Alchemist to Lv 28, Armorer to Lv 26 and Carpenter to Lv 25 — so no single class can finish it unaided.

One intermediate outranks the result: Clear Glass Lens is a Lv 28 Alchemist recipe feeding a Lv 27 craft, so that step, not the last one, is the real gate.

All 6 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.
