Sky Rat Harness of Scouting ★★★★

Taken all the way down to base materials, one Sky Rat Harness of Scouting is 3 crafting steps deep and needs 7 intermediates — Grade 2 Dexterity Dissolvent ×2, Peteinosaur Leather ×2, Chimerical Felt ×1 and 4 others — which resolve to 12 distinct raw materials totalling 28 units, plus 50 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,414 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 11 Earth Cluster, 7 Earth Crystal, 7 Fire Crystal and 6 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60 and Weaver to Lv 58 — so no single class can finish it unaided.

7 of the 12 raw materials come out of the ground, and 2 of them are time-gated: Cloud Mythril Ore (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and Clary Sage (0:00, 20:00). 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.
