Hallowed Ramie Cloth

Taken all the way down to base materials, one Hallowed Ramie Cloth is 3 crafting steps deep and needs 4 intermediates — Hallowed Water ×2, Ramie Cloth ×1, Ramie Thread ×2 and 1 other — which resolve to 4 distinct raw materials totalling 11 units, plus 16 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 737 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 11 are burned by the intermediates, so the real crystal cost is 9 Lightning Crystal, 5 Water Crystal and 2 Lightning Shard.

The chain crosses two disciplines — Weaver to Lv 56 and Alchemist to Lv 56 — so no single class can finish it unaided.

All 4 raw materials are gathered, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Hallowed Ramie Cloth is itself consumed by 25 further recipes, spanning four of the eight crafting classes.
