Thunderstorm Axe

Taken all the way down to base materials, one Thunderstorm Axe is 4 crafting steps deep and needs 6 intermediates — Inferno Axe ×1, Silver Ingot ×1, Brass Ingot ×1 and 3 others — which resolve to 5 distinct raw materials totalling 21 units, plus 17 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 874 of the 1,932 Blacksmith ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 9 Fire Shard, 4 Earth Shard and 4 Wind Shard.

The chain crosses three disciplines — Blacksmith to Lv 26, Goldsmith to Lv 23 and Carpenter to Lv 10 — so no single class can finish it unaided.

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
