Weighing Scale

Taken all the way down to base materials, one Weighing Scale is 3 crafting steps deep and needs 4 intermediates — Brass Ingot ×3, Brass Rings ×2, Silver Ingot ×2 and 1 other — which resolve to 4 distinct raw materials totalling 18 units, plus 16 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 1,038 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 11 are burned by the intermediates, so the real crystal cost is 14 Wind Shard and 2 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 27 and Carpenter to Lv 21 — 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
