Bronze Spear

Taken all the way down to base materials, one Bronze Spear is 2 crafting steps deep and needs 3 intermediates — Bronze Ingot ×1, Fish Oil ×1 and Maple Lumber ×1 — which resolve to 4 distinct raw materials totalling 8 units, plus 5 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 541 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

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

The chain crosses three disciplines — Carpenter to Lv 6, Alchemist to Lv 10 and Blacksmith to Lv 1 — so no single class can finish it unaided.

One intermediate outranks the result: Fish Oil is a Lv 10 Alchemist recipe feeding a Lv 6 craft, so that step, not the last one, is the real gate.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.
