Saurian Gloves of Healing ★★★

Taken all the way down to base materials, one Saurian Gloves of Healing is 3 crafting steps deep and needs 5 intermediates — Silk Thread ×2, Terminus Putty ×2, Saurian Leather ×1 and 2 others — which resolve to 10 distinct raw materials totalling 15 units, plus 19 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 826 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 5 Lightning Shard, 4 Earth Cluster, 3 Lightning Crystal and 4 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 50, Alchemist to Lv 50 and Weaver to Lv 50 — so no single class can finish it unaided.

4 of the 10 raw materials come out of the ground, and 2 of them are time-gated: Shroud Tea Leaves (2:00) and Silkworm Cocoon (1:00). The widest gap between consecutive opening times is 23 Eorzean hours, about 67 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
