Astroscope

Taken all the way down to base materials, one Astroscope is 3 crafting steps deep and needs 5 intermediates — Electrum Ingot ×4, Mahogany Lumber ×3, Raptor Leather ×2 and 2 others — which resolve to 7 distinct raw materials totalling 32 units, plus 62 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,738 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 50 are burned by the intermediates, so the real crystal cost is 41 Wind Shard, 10 Earth Shard, 6 Fire Shard and 1 other kind.

The chain crosses four disciplines — Goldsmith to Lv 49, Leatherworker to Lv 41, Carpenter to Lv 39 and Alchemist to Lv 28 — so no single class can finish it unaided.

6 of the 7 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Astroscope is itself consumed by 1 further recipe, all of them Carpenter recipes.
