Oriental Altar ★★★

Taken all the way down to base materials, one Oriental Altar is 3 crafting steps deep and needs 5 intermediates — Ancient Lumber ×4, Bronze Ingot ×1, Clear Glass Lens ×1 and 2 others — which resolve to 10 distinct raw materials totalling 20 units, plus 23 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 791 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 10 Wind Cluster, 5 Ice Cluster, 5 Water Shard and 2 other kinds.

The chain crosses four disciplines — Carpenter to Lv 50, Alchemist to Lv 28, Goldsmith to Lv 23 and Blacksmith to Lv 1 — so no single class can finish it unaided.

8 of the 10 raw materials come out of the ground, and one of them is time-gated: Scarlet Sap (3:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
