Oak Longbow

Taken all the way down to base materials, one Oak Longbow is 2 crafting steps deep and needs 3 intermediates — Linen Yarn ×1, Oak Lumber ×1 and Steel Ingot ×1 — which resolve to 5 distinct raw materials totalling 10 units, plus 14 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 568 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 7 Wind Shard, 3 Ice Shard, 2 Fire Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 35, Weaver to Lv 32 and Blacksmith to Lv 26 — 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
