Cassia Block ★

Taken all the way down to base materials, one Cassia Block is 2 crafting steps deep and needs 2 intermediates — Astral Oil ×1 and Cassia Lumber ×1 — which resolve to 6 distinct raw materials totalling 18 units, plus 9 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 740 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 4 Wind Cluster, 2 Ice Cluster, 2 Water Cluster and 1 other kind.

The chain crosses two disciplines — Carpenter to Lv 60 and Alchemist to Lv 60 — so no single class can finish it unaided.

2 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Astral Moraine (0:00, 12:00) and Seventh Heaven (4:00, 16:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Cassia Block is itself consumed by 2 further recipes, all of them Carpenter recipes.
