Aurum Regis Cylinder

Taken all the way down to base materials, one Aurum Regis Cylinder is 2 crafting steps deep and needs 2 intermediates — Aurum Regis Nugget ×1 and Cloud Mica Whetstone ×1 — which resolve to 3 distinct raw materials totalling 9 units, plus 20 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 764 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 15 Wind Crystal and 5 Fire Crystal.

Every step is Goldsmith work, from a Lv 56 intermediate up to the Lv 59 finish, so one class covers the whole chain.

All 3 raw materials are gathered, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Aurum Regis Cylinder is itself consumed by 2 further recipes, all of them Goldsmith recipes.
