Longbow of Sanctifying Light ★★

Taken all the way down to base materials, one Longbow of Sanctifying Light is 2 crafting steps deep and needs 3 intermediates — Lunar Adamantite Ingot ×4, Chondrite Ingot ×1 and Golden Silk ×1 — which resolve to 8 distinct raw materials totalling 45 units, plus 44 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,645 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 15 Earth Cluster, 15 Fire Cluster, 8 Fire Crystal and 2 other kinds.

The chain crosses two disciplines — Blacksmith to Lv 90 and Weaver to Lv 90 — so no single class can finish it unaided.

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Golden Cocoon (8:00, 20:00) and Lunar Adamantite Ore (2:00, 14:00). The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
