Connoisseur's Astroscope ★★

Taken all the way down to base materials, one Connoisseur's Astroscope is 3 crafting steps deep and needs 3 intermediates — Chondrite Ingot ×1, Star Quartz ×1 and Annite Whetstone ×1 — which resolve to 5 distinct raw materials totalling 14 units, plus 30 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 907 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 16 Wind Crystal, 8 Fire Crystal, 4 Wind Cluster and 1 other kind.

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

4 of the 5 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

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