Watcher's Palace Ceiling Lamp

Taken all the way down to base materials, one Watcher's Palace Ceiling Lamp is 3 crafting steps deep and needs 5 intermediates — Crystal Glass ×5, Phrygian Gold Ingot ×4, Star Quartz ×3 and 2 others — which resolve to 9 distinct raw materials totalling 79 units, plus 131 crystals.

That bill outweighs 13,405 of the 13,602 recipes tracked here and 1,911 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 115 are burned by the intermediates, so the real crystal cost is 80 Wind Crystal, 25 Water Crystal, 10 Water Shard and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 90, Goldsmith to Lv 88 and Alchemist to Lv 50 — so no single class can finish it unaided.

7 of the 9 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
