Rousing Chronometer

Taken all the way down to base materials, one Rousing Chronometer is 3 crafting steps deep and needs 4 intermediates — Chondrite Ingot ×3, Phrygian Gold Ingot ×2, Star Quartz ×2 and 1 other — which resolve to 6 distinct raw materials totalling 44 units, plus 88 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,595 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 72 are burned by the intermediates, so the real crystal cost is 48 Wind Crystal, 32 Fire Crystal and 8 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 90 and Goldsmith to Lv 88 — so no single class can finish it unaided.

All 6 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, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
