Bluespirit Halfheart Saw

Taken all the way down to base materials, one Bluespirit Halfheart Saw is 2 crafting steps deep and needs 2 intermediates — Bluespirit Tile ×3 and White Ash Lumber ×1 — which resolve to 3 distinct raw materials totalling 19 units, plus 41 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 804 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 28 Fire Crystal, 7 Wind Crystal and 6 Earth Crystal.

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

All 3 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, Bluespirit Tile has the widest use: 72 recipes call for it, spanning six of the eight crafting classes.
