Crystarium Bench

Taken all the way down to base materials, one Crystarium Bench is 4 crafting steps deep and needs 8 intermediates — Darksteel Plate ×3, Titanbronze Ingot ×3, Steppe Serge ×2 and 5 others — which resolve to 9 distinct raw materials totalling 48 units, plus 86 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,340 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 14 of those crystals go into the final step; the other 72 are burned by the intermediates, so the real crystal cost is 39 Fire Crystal, 16 Ice Crystal, 10 Fire Shard and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 77, Blacksmith to Lv 76, Weaver to Lv 66 and Alchemist to Lv 25 — so no single class can finish it unaided.

7 of the 9 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
