Perfect Mortar ★★★

Taken all the way down to base materials, one Perfect Mortar is 2 crafting steps deep and needs 1 intermediate — Mahogany Lumber ×1 — which resolves to 3 distinct raw materials totalling 5 units, plus 8 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 453 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 5 Wind Shard, 2 Ice Cluster and 1 Earth Cluster.

The chain crosses two disciplines — Armorer to Lv 50 and Carpenter to Lv 39 — so no single class can finish it unaided.

1 of the 3 raw materials matches a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Mahogany Lumber has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
