Titanium Battleaxe

Taken all the way down to base materials, one Titanium Battleaxe is 3 crafting steps deep and needs 7 intermediates — Titanium Ingot ×3, Titanium Rivets ×2, Hallowed Chestnut Lumber ×1 and 4 others — which resolve to 10 distinct raw materials totalling 63 units, plus 70 crystals.

That bill outweighs 13,204 of the 13,602 recipes tracked here and 1,845 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 61 are burned by the intermediates, so the real crystal cost is 48 Fire Crystal, 9 Water Crystal, 9 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 57, Alchemist to Lv 56 and Carpenter to Lv 56 — so no single class can finish it unaided.

7 of the 10 raw materials come out of the ground, 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, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
