Summoning Bell ★★★

Taken all the way down to base materials, one Summoning Bell is 2 crafting steps deep and needs 2 intermediates — Ancient Lumber ×1 and Wolfram Ingot ×1 — which resolve to 6 distinct raw materials totalling 6 units, plus 9 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 467 of the 1,932 Blacksmith 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 Fire Cluster, 2 Earth Cluster, 2 Wind Cluster and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 50 and Carpenter to Lv 50 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Ferberite (3:00) and Scarlet Sap (3:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Wolfram Ingot has the widest use: 107 recipes call for it, spanning five of the eight crafting classes.
