Sky Pirate's Helm of Maiming ★★

Taken all the way down to base materials, one Sky Pirate's Helm of Maiming is 3 crafting steps deep and needs 6 intermediates — Titanium Alloy Ingot ×2, Chimerical Felt ×1, Grade 1 Strength Dissolvent ×1 and 3 others — which resolve to 12 distinct raw materials totalling 41 units, plus 37 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,267 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 5 Lightning Crystal, 4 Earth Cluster and 4 other kinds.

The chain crosses four disciplines — Armorer to Lv 60, Blacksmith to Lv 60, Weaver to Lv 58 and Alchemist to Lv 53 — 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: Sphalerite (2:00, 6:00, 10:00, 14:00, 18:00, 22:00) and Volcanic Rock Salt (17:00). 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.
