Simple Fountain

Taken all the way down to base materials, one Simple Fountain is 2 crafting steps deep and needs 1 intermediate — Firebricks ×5 — which resolves to 5 distinct raw materials totalling 27 units, plus 21 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,605 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 8 Fire Crystal, 8 Wind Crystal and 5 Water Shard.

The chain crosses two disciplines — Goldsmith to Lv 90 and Alchemist to Lv 18 — 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, Firebricks has the widest use: 27 recipes call for it, spanning three of the eight crafting classes.
