Cobalt Trident

Taken all the way down to base materials, one Cobalt Trident is 2 crafting steps deep and needs 3 intermediates — Cobalt Ingot ×3, Mahogany Lumber ×1 and Shark Oil ×1 — which resolve to 5 distinct raw materials totalling 14 units, plus 36 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 639 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 15 Fire Shard, 11 Wind Shard, 5 Ice Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 47, Blacksmith to Lv 42 and Alchemist to Lv 41 — so no single class can finish it unaided.

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

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