Bomb Cauldron

Taken all the way down to base materials, one Bomb Cauldron is 2 crafting steps deep and needs 2 intermediates — Dwarven Mythril Ingot ×7 and Growth Formula Kappa ×4 — which resolve to 7 distinct raw materials totalling 60 units, plus 91 crystals.

That bill outweighs 13,112 of the 13,602 recipes tracked here and 1,387 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 77 are burned by the intermediates, so the real crystal cost is 49 Fire Crystal, 28 Water Crystal, 7 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 80, Blacksmith to Lv 78 and Alchemist to Lv 76 — so no single class can finish it unaided.

5 of the 7 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, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
