Oasis Lamppost

Taken all the way down to base materials, one Oasis Lamppost is 3 crafting steps deep and needs 4 intermediates — Clear Glass Lens ×2, Cut Stone ×2, Steel Ingot ×2 and 1 other — which resolve to 7 distinct raw materials totalling 20 units, plus 26 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 851 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 10 Water Shard, 7 Fire Shard, 6 Wind Shard and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 32, Goldsmith to Lv 30 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.

Of the intermediates, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
