Factory Railing

Taken all the way down to base materials, one Factory Railing is 2 crafting steps deep and needs 2 intermediates — Dwarven Mythril Ingot ×4 and Titanbronze Ingot ×2 — which resolve to 5 distinct raw materials totalling 31 units, plus 56 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,210 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 42 are burned by the intermediates, so the real crystal cost is 49 Fire Crystal and 7 Earth Crystal.

Every step is Blacksmith work, from a Lv 76 intermediate up to the Lv 80 finish, so one class covers the whole chain.

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, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
