Tier 2 Aquarium

Taken all the way down to base materials, one Tier 2 Aquarium is 3 crafting steps deep and needs 7 intermediates — Hallowed Chestnut Lumber ×4, Gold Ingot ×3, Crystal Glass ×1 and 4 others — which resolve to 14 distinct raw materials totalling 61 units, plus 80 crystals.

That bill outweighs 13,148 of the 13,602 recipes tracked here and 1,425 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 70 are burned by the intermediates, so the real crystal cost is 41 Wind Crystal, 20 Water Crystal, 6 Wind Cluster and 5 other kinds.

The chain crosses three disciplines — Carpenter to Lv 58, Alchemist to Lv 56 and Goldsmith to Lv 50 — so no single class can finish it unaided.

10 of the 14 raw materials come out of the ground, and 3 of them are time-gated: Abalathian Mistletoe (6:00, 18:00), Gold Ore (9:00) and 1 other. The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
