Skybuilders' Charcoal

Taken all the way down to base materials, one Skybuilders' Charcoal is 2 crafting steps deep and needs 1 intermediate — Lanolin ×1 — which resolves to 3 distinct raw materials totalling 13 units, plus 11 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 1,216 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 5 Water Shard, 4 Water Crystal and 2 Lightning Crystal.

Every step is Alchemist work, from a Lv 40 intermediate up to the Lv 60 finish, so one class covers the whole chain.

2 of the 3 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, Lanolin has the widest use: 4 recipes call for it, spanning three of the eight crafting classes.
