Hallowed Chestnut Composite Bow

Taken all the way down to base materials, one Hallowed Chestnut Composite Bow is 3 crafting steps deep and needs 7 intermediates — Hallowed Chestnut Lumber ×2, Hardsilver Ingot ×2, Electrum Ingot ×1 and 4 others — which resolve to 10 distinct raw materials totalling 48 units, plus 62 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,342 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 53 are burned by the intermediates, so the real crystal cost is 41 Wind Crystal, 10 Water Crystal, 5 Wind Shard and 2 other kinds.

The chain crosses four disciplines — Carpenter to Lv 56, Alchemist to Lv 56, Goldsmith to Lv 56 and Weaver to Lv 54 — so no single class can finish it unaided.

All 10 raw materials are gathered, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
