Arbor Flooring

Taken all the way down to base materials, one Arbor Flooring is 3 crafting steps deep and needs 3 intermediates — Growth Formula Gamma ×4, Aldgoat Leather ×2 and Quicksilver ×4 — which resolve to 6 distinct raw materials totalling 22 units, plus 24 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,157 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 16 Water Shard, 5 Earth Shard and 3 Wind Shard.

The chain crosses two disciplines — Leatherworker to Lv 30 and Alchemist to Lv 30 — so no single class can finish it unaided.

4 of the 6 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Aldgoat Leather has the widest use: 98 recipes call for it, spanning seven of the eight crafting classes.
