Mormorion Ring of Healing

Taken all the way down to base materials, one Mormorion Ring of Healing is 2 crafting steps deep and needs 3 intermediates — Basilisk Whetstone ×1, Grade 1 Mind Dissolvent ×1 and Mormorion ×1 — which resolve to 6 distinct raw materials totalling 12 units, plus 20 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 862 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 8 Wind Crystal, 5 Wind Shard, 4 Water Crystal and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 54 and Alchemist to Lv 54 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Basilisk Whetstone has the widest use: 55 recipes call for it, spanning two of the eight crafting classes.
