Titanium Alloy Mirror ★

Taken all the way down to base materials, one Titanium Alloy Mirror is 3 crafting steps deep and needs 3 intermediates — Holy Water ×1, Titanium Alloy Square ×1 and Titanium Nugget ×1 — which resolve to 9 distinct raw materials totalling 16 units, plus 13 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 1,240 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 4 Fire Crystal, 3 Water Crystal, 2 Ice Cluster and 3 other kinds.

The chain crosses three disciplines — Alchemist to Lv 60, Armorer to Lv 60 and Blacksmith to Lv 54 — so no single class can finish it unaided.

7 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Sphalerite (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
