Wavesoul Fount ★★

Taken all the way down to base materials, one Wavesoul Fount is 2 crafting steps deep and needs 2 intermediates — Darksteel Nugget ×10 and Rose Gold Nugget ×2 — which resolve to 5 distinct raw materials totalling 45 units, plus 46 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,645 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 30 Fire Crystal, 10 Water Crystal and 6 Wind Crystal.

The chain crosses two disciplines — Blacksmith to Lv 50 and Goldsmith to Lv 50 — so no single class can finish it unaided.

4 of the 5 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Gold Ore (9:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
