Blade of Sanctifying Light ★★

Taken all the way down to base materials, one Blade of Sanctifying Light is 2 crafting steps deep and needs 3 intermediates — Lunar Adamantite Ingot ×4, Annite Whetstone ×1 and Rhodium Ingot ×1 — which resolve to 7 distinct raw materials totalling 43 units, plus 44 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,542 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, 15 Earth Cluster, 8 Wind 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.

3 of the 7 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, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
