Manor Harp ★★★

Taken all the way down to base materials, one Manor Harp is 2 crafting steps deep and needs 3 intermediates — Dew Thread ×4, Mahogany Lumber ×4 and Spruce Lumber ×4 — which resolve to 5 distinct raw materials totalling 31 units, plus 37 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,086 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 20 Wind Shard, 12 Wind Crystal, 2 Lightning Shard and 2 other kinds.

The chain crosses two disciplines — Carpenter to Lv 50 and Weaver to Lv 23 — so no single class can finish it unaided.

2 of the 5 raw materials come out of the ground, and one of them is time-gated: Spruce Log (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Mahogany Lumber has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
