Durium Astrometer

Taken all the way down to base materials, one Durium Astrometer is 3 crafting steps deep and needs 5 intermediates — Durium Nugget ×3, Enchanted Durium Ink ×1, Kyanite ×1 and 2 others — which resolve to 8 distinct raw materials totalling 33 units, plus 38 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,755 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 19 Wind Crystal, 8 Fire Crystal, 7 Fire Shard and 1 other kind.

The chain crosses four disciplines — Goldsmith to Lv 65, Alchemist to Lv 64, Blacksmith to Lv 64 and Culinarian to Lv 63 — so no single class can finish it unaided.

All 8 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, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
