Mossy Rock

Taken all the way down to base materials, one Mossy Rock is 3 crafting steps deep and needs 2 intermediates — Growth Formula Gamma ×4 and Quicksilver ×4 — which resolve to 4 distinct raw materials totalling 28 units, plus 23 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,345 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 20 Water Shard and 3 Lightning Shard.

Every step is Alchemist work, from a Lv 1 intermediate up to the Lv 33 finish, so one class covers the whole chain.

3 of the 4 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, Growth Formula Gamma has the widest use: 31 recipes call for it, spanning four of the eight crafting classes.
