Pactmaker's Grinding Wheel ★★

Taken all the way down to base materials, one Pactmaker's Grinding Wheel is 3 crafting steps deep and needs 4 intermediates — Eblan Danburite ×3, Mempisang Lumber ×3, Star Quartz ×1 and 1 other — which resolve to 8 distinct raw materials totalling 46 units, plus 58 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,328 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 52 are burned by the intermediates, so the real crystal cost is 21 Wind Cluster, 16 Wind Crystal, 12 Ice Cluster and 1 other kind.

The chain crosses two disciplines — Carpenter to Lv 90 and Goldsmith to Lv 90 — so no single class can finish it unaided.

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Mempisang Log (6:00, 18:00) and Raw Eblan Danburite (0:00, 12:00). The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
