Wall Chronometer

Taken all the way down to base materials, one Wall Chronometer is 3 crafting steps deep and needs 5 intermediates — Cobalt Ingot ×5, Cobalt Rivets ×4, Electrum Ingot ×2 and 2 others — which resolve to 6 distinct raw materials totalling 32 units, plus 80 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,738 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 68 are burned by the intermediates, so the real crystal cost is 51 Fire Shard and 29 Wind Shard.

The chain crosses three disciplines — Goldsmith to Lv 48, Carpenter to Lv 45 and Blacksmith to Lv 43 — 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
