Riviera Flower Vase

Taken all the way down to base materials, one Riviera Flower Vase is 3 crafting steps deep and needs 3 intermediates — Iron Ingot ×3, Growth Formula Beta ×2 and Quicksilver ×2 — which resolve to 5 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 Fire Shard and 1 Lightning Shard.

The chain crosses two disciplines — Alchemist to Lv 23 and Blacksmith to Lv 16 — 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, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
