Petalite Choker of Slaying

Taken all the way down to base materials, one Petalite Choker of Slaying is 3 crafting steps deep and needs 5 intermediates — Dwarven Mythril Nugget ×2, Grade 1 Strength Alkahest ×1, Manasilver Nugget ×1 and 2 others — which resolve to 9 distinct raw materials totalling 25 units, plus 55 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,507 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 41 are burned by the intermediates, so the real crystal cost is 42 Wind Crystal, 7 Fire Crystal and 6 Water Crystal.

The chain crosses two disciplines — Goldsmith to Lv 79 and Alchemist to Lv 73 — so no single class can finish it unaided.

8 of the 9 raw materials come out of the ground, and one of them is time-gated: Raw Petalite (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Dwarven Mythril Nugget has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
