Glade Open-shelf Bookcase ★

Taken all the way down to base materials, one Glade Open-shelf Bookcase is 2 crafting steps deep and needs 3 intermediates — Spruce Lumber ×7, Cobalt Ingot ×4 and Jadeite ×3 — which resolve to 4 distinct raw materials totalling 36 units, plus 61 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,184 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 20 Fire Shard, 15 Wind Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 50, Blacksmith to Lv 42 and Goldsmith to Lv 40 — so no single class can finish it unaided.

All 4 raw materials are gathered, and one of them is time-gated: Spruce Log (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
