Chocobo Weathervane

Taken all the way down to base materials, one Chocobo Weathervane is 3 crafting steps deep and needs 3 intermediates — Cobalt Ingot ×8, Cobalt Rivets ×4 and Rosewood Lumber ×4 — which resolve to 3 distinct raw materials totalling 36 units, plus 96 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 12 of those crystals go into the final step; the other 84 are burned by the intermediates, so the real crystal cost is 66 Fire Shard, 24 Wind Shard and 6 Earth Shard.

The chain crosses two disciplines — Blacksmith to Lv 50 and Carpenter to Lv 45 — so no single class can finish it unaided.

All 3 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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
