Indirect Stand Lighting ★★★

Taken all the way down to base materials, one Indirect Stand Lighting is 3 crafting steps deep and needs 6 intermediates — Titanium Alloy Ingot ×3, Titanium Rivets ×3, Wolfram Ingot ×3 and 3 others — which resolve to 12 distinct raw materials totalling 71 units, plus 66 crystals.

That bill outweighs 13,309 of the 13,602 recipes tracked here and 1,406 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 61 are burned by the intermediates, so the real crystal cost is 36 Fire Crystal, 12 Fire Cluster, 8 Earth Cluster and 3 other kinds.

The chain crosses three disciplines — Armorer to Lv 60, Blacksmith to Lv 60 and Alchemist to Lv 50 — so no single class can finish it unaided.

9 of the 12 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 Ferberite (3:00). 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.
