Bluespirit Round Knife

Taken all the way down to base materials, one Bluespirit Round Knife is 2 crafting steps deep and needs 4 intermediates — Bluespirit Tile ×1, Hard Mudstone Whetstone ×1, Manasilver Nugget ×1 and 1 other — which resolve to 6 distinct raw materials totalling 17 units, plus 40 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 757 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 20 Wind Crystal, 14 Fire Crystal and 6 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 75, Carpenter to Lv 74 and Goldsmith to Lv 74 — so no single class can finish it unaided.

All 6 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, Manasilver Nugget has the widest use: 83 recipes call for it, spanning seven of the eight crafting classes.
