Sky Rat Fingerless Gloves of Casting ★★★★

Taken all the way down to base materials, one Sky Rat Fingerless Gloves of Casting is 3 crafting steps deep and needs 7 intermediates — Chimerical Felt ×1, Grade 2 Intelligence Dissolvent ×1, High Mythrite Nugget ×1 and 4 others — which resolve to 13 distinct raw materials totalling 26 units, plus 45 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,336 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 7 Earth Crystal, 7 Fire Crystal, 7 Lightning Cluster and 5 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60 and Weaver to Lv 60 — so no single class can finish it unaided.

8 of the 13 raw materials come out of the ground, and 3 of them are time-gated: Chysahl Greens (0:00, 4:00, 8:00, 12:00, 16:00, 20:00), Stormcloud Cotton Boll (0:00, 4:00, 8:00, 12:00, 16:00, 20:00) and 1 other. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Chimerical Felt has the widest use: 113 recipes call for it, spanning six of the eight crafting classes.
