Log Rack

Taken all the way down to base materials, one Log Rack is 2 crafting steps deep and needs 3 intermediates — Chondrite Ingot ×7, Manganese Ingot ×4 and Firewood ×1 — which resolve to 5 distinct raw materials totalling 75 units, plus 106 crystals.

That bill outweighs 13,370 of the 13,602 recipes tracked here and 1,905 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 90 are burned by the intermediates, so the real crystal cost is 96 Fire Crystal, 8 Earth Crystal, 1 Ice Shard and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 90 and Carpenter to Lv 12 — 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, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
