Oasis Flower Vase

Taken all the way down to base materials, one Oasis Flower Vase is 3 crafting steps deep and needs 3 intermediates — Brass Ingot ×3, Growth Formula Beta ×2 and Quicksilver ×2 — which resolve to 6 distinct raw materials totalling 20 units, plus 10 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,279 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 6 Water Shard, 3 Wind Shard and 1 Lightning Shard.

The chain crosses two disciplines — Alchemist to Lv 23 and Goldsmith to Lv 14 — so no single class can finish it unaided.

5 of the 6 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, Brass Ingot has the widest use: 94 recipes call for it, spanning seven of the eight crafting classes.
