Brass Spear

Taken all the way down to base materials, one Brass Spear is 2 crafting steps deep and needs 4 intermediates — Brass Ingot ×1, Bronze Ingot ×1, Fish Oil ×1 and 1 other — which resolve to 5 distinct raw materials totalling 11 units, plus 6 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 581 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 3 Wind Shard, 1 Fire Shard, 1 Ice Shard and 1 other kind.

The chain crosses four disciplines — Carpenter to Lv 14, Goldsmith to Lv 14, Alchemist to Lv 10 and Blacksmith to Lv 1 — 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, Brass Ingot has the widest use: 94 recipes call for it, spanning seven of the eight crafting classes.
