Bluebird Mobile

Taken all the way down to base materials, one Bluebird Mobile is 2 crafting steps deep and needs 3 intermediates — Lignum Vitae Lumber ×4, Sandteak Lumber ×2 and Titanbronze Nugget ×2 — which resolve to 4 distinct raw materials totalling 34 units, plus 70 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,145 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 63 Wind Crystal and 7 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 80 and Goldsmith to Lv 76 — 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, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
