Indoor Pond

Taken all the way down to base materials, one Indoor Pond is 2 crafting steps deep and needs 2 intermediates — Firebricks ×10 and Growth Formula Kappa ×4 — which resolve to 6 distinct raw materials totalling 56 units, plus 52 crystals.

That bill outweighs 12,997 of the 13,602 recipes tracked here and 1,546 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 35 Water Crystal, 10 Water Shard and 7 Lightning Crystal.

Every step is Alchemist work, from a Lv 18 intermediate up to the Lv 80 finish, so one class covers the whole chain.

4 of the 6 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, Growth Formula Kappa has the widest use: 40 recipes call for it, spanning four of the eight crafting classes.
