Titanium Lump Hammer

Taken all the way down to base materials, one Titanium Lump Hammer is 3 crafting steps deep and needs 8 intermediates — Titanium Ingot ×2, Hallowed Chestnut Lumber ×1, Mythrite Ingot ×1 and 5 others — which resolve to 13 distinct raw materials totalling 48 units, plus 51 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,712 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 42 are burned by the intermediates, so the real crystal cost is 29 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.

10 of the 13 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.
