Ash Mask

Taken all the way down to base materials, one Ash Mask is 2 crafting steps deep and needs 3 intermediates — Ash Lumber ×1, Fish Oil ×1 and Leather ×1 — which resolve to 3 distinct raw materials totalling 6 units, plus 5 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 486 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 Earth Shard, 1 Ice Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 14, Alchemist to Lv 10 and Leatherworker to Lv 1 — so no single class can finish it unaided.

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

Of the intermediates, Ash Lumber has the widest use: 60 recipes call for it, spanning seven of the eight crafting classes.
