Silvergrace Rapier ★★★

Taken all the way down to base materials, one Silvergrace Rapier is 4 crafting steps deep and needs 8 intermediates — Grade 3 Reisui of Intelligence ×3, Silvergrace Ingot ×3, Rhodonite ×2 and 5 others — which resolve to 17 distinct raw materials totalling 57 units, plus 48 crystals.

That bill outweighs 13,047 of the 13,602 recipes tracked here and 2,109 of the 2,216 Goldsmith ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 18 Wind Crystal, 8 Fire Cluster, 6 Fire Crystal and 5 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 70, Alchemist to Lv 70, Blacksmith to Lv 70 and Leatherworker to Lv 64 — so no single class can finish it unaided.

11 of the 17 raw materials come out of the ground, and 4 of them are time-gated: Gyr Abanian Spring Water (10:00, 22:00), Nightsteel Ore (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
