True Barding of Light ★★★

Taken all the way down to base materials, one True Barding of Light is 2 crafting steps deep and needs 3 intermediates — Cobalt Alloy Ingot ×3, Dwarven Mythril Ingot ×2 and Purpure Bead ×2 — which resolve to 7 distinct raw materials totalling 41 units, plus 38 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,267 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 14 Fire Crystal, 10 Fire Cluster, 8 Earth Cluster and 2 other kinds.

The chain crosses three disciplines — Armorer to Lv 80, Blacksmith to Lv 80 and Goldsmith to Lv 80 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Fireheart Cobalt (2:00, 14:00) and Purpure Shell Chip (6:00, 18:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
