Cannonballs

Taken all the way down to base materials, one Cannonballs is 3 crafting steps deep and needs 3 intermediates — Mythril Ingot ×4, Cobalt Plate ×2 and Cobalt Ingot ×4 — which resolve to 4 distinct raw materials totalling 26 units, plus 57 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,087 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 42 Fire Shard, 10 Ice Shard and 5 Earth Shard.

The chain crosses two disciplines — Blacksmith to Lv 45 and Armorer to Lv 43 — so no single class can finish it unaided.

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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
