Glade Cottage Roof (Composite)

Taken all the way down to base materials, one Glade Cottage Roof (Composite) is 3 crafting steps deep and needs 5 intermediates — Roof Tile ×15, Elm Lumber ×10, Iron Joint Plate ×10 and 2 others — which resolve to 4 distinct raw materials totalling 135 units, plus 77 crystals.

That bill outweighs 13,522 of the 13,602 recipes tracked here and 1,579 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 65 are burned by the intermediates, so the real crystal cost is 30 Fire Shard, 23 Water Shard, 10 Ice Shard and 2 other kinds.

The chain crosses four disciplines — Alchemist to Lv 23, Blacksmith to Lv 16, Carpenter to Lv 16 and Armorer to Lv 15 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
