Hallowed Chestnut Wand

Taken all the way down to base materials, one Hallowed Chestnut Wand is 3 crafting steps deep and needs 7 intermediates — Growth Formula Epsilon ×3, Hallowed Chestnut Lumber ×1, Hardsilver Ingot ×1 and 4 others — which resolve to 9 distinct raw materials totalling 40 units, plus 44 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,466 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 35 are burned by the intermediates, so the real crystal cost is 19 Water Crystal, 18 Wind Crystal, 4 Lightning Crystal and 1 other kind.

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

8 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Abalathian Mistletoe (6:00, 18:00) and Volcanic Rock Salt (17:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Hardsilver Ingot has the widest use: 117 recipes call for it, spanning seven of the eight crafting classes.
