Paladin's Arms of Sanctifying Light ★★

Taken all the way down to base materials, one Paladin's Arms of Sanctifying Light is 3 crafting steps deep and needs 4 intermediates — Lunar Adamantite Ingot ×3, Rhodium Ingot ×2, Star Quartz ×1 and 1 other — which resolve to 8 distinct raw materials totalling 46 units, plus 52 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,675 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 18 Fire Cluster, 16 Wind Crystal, 12 Earth Cluster 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, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
