Glade Mansion Roof (Stone) ★

Taken all the way down to base materials, one Glade Mansion Roof (Stone) is 3 crafting steps deep and needs 6 intermediates — Cobalt Joint Plate ×10, Cobalt Nails ×10, Felt Lining ×10 and 3 others — which resolve to 8 distinct raw materials totalling 170 units, plus 305 crystals.

That bill outweighs 13,542 of the 13,602 recipes tracked here and 1,966 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 20 of those crystals go into the final step; the other 285 are burned by the intermediates, so the real crystal cost is 150 Fire Shard, 50 Ice Shard, 50 Lightning Shard and 3 other kinds.

The chain crosses five disciplines — Weaver to Lv 50, Carpenter to Lv 50, Armorer to Lv 44, Blacksmith to Lv 44 and Alchemist to Lv 25 — so no single class can finish it unaided.

7 of the 8 raw materials come out of the ground, 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.
