Courtly Lover's Wristlet of Healing ★★★★

Taken all the way down to base materials, one Courtly Lover's Wristlet of Healing is 3 crafting steps deep and needs 5 intermediates — Black Star ×1, Double Duraluminum Ingot ×1, Grade 4 Gemsap of Mind ×1 and 2 others — which resolve to 10 distinct raw materials totalling 26 units, plus 40 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,562 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 9 Fire Cluster, 8 Water Crystal, 8 Wind Crystal and 4 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 100, Alchemist to Lv 100 and Blacksmith to Lv 100 — so no single class can finish it unaided.

7 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Dense Aluminum Ore (10:00, 22:00), Rose Garnet Ore (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
