Cobalt Sledgehammer

Taken all the way down to base materials, one Cobalt Sledgehammer is 2 crafting steps deep and needs 3 intermediates — Cobalt Ingot ×1, Horn Glue ×1 and Rosewood Lumber ×1 — which resolve to 4 distinct raw materials totalling 8 units, plus 24 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 529 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 10 Fire Shard, 6 Wind Shard, 5 Earth Shard and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 44, Carpenter to Lv 45 and Alchemist to Lv 30 — so no single class can finish it unaided.

One intermediate outranks the result: Rosewood Lumber is a Lv 45 Carpenter recipe feeding a Lv 44 craft, so that step, not the last one, is the real gate.

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.
