Gunblade of Sanctifying Light ★★

Taken all the way down to base materials, one Gunblade of Sanctifying Light is 2 crafting steps deep and needs 3 intermediates — Lunar Adamantite Ingot ×3, Rhodium Ingot ×2 and Chondrite Ingot ×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 18 Fire Cluster, 12 Earth Cluster, 8 Fire Crystal and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 90 and Goldsmith 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: Lunar Adamantite Ore (2:00, 14:00) and Rhodium Sand (4:00, 16:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

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