Glade Partition Door ★★★

Taken all the way down to base materials, one Glade Partition Door is 3 crafting steps deep and needs 5 intermediates — Rosewood Lumber ×4, Ancient Lumber ×3, Silver Ingot ×1 and 2 others — which resolve to 6 distinct raw materials totalling 24 units, plus 42 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 904 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 26 Wind Shard, 8 Wind Cluster, 4 Ice Cluster and 2 other kinds.

The chain crosses four disciplines — Carpenter to Lv 50, Armorer to Lv 26, Blacksmith to Lv 26 and Goldsmith to Lv 23 — so no single class can finish it unaided.

5 of the 6 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.
