Ash Mask (Lapis Lazuli)

Taken all the way down to base materials, one Ash Mask (Lapis Lazuli) is 2 crafting steps deep and needs 4 intermediates — Ash Lumber ×1, Clove Oil ×1, Lapis Lazuli ×1 and 1 other — which resolve to 4 distinct raw materials totalling 7 units, plus 6 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 509 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 3 Wind Shard, 1 Earth Shard, 1 Ice Shard and 1 other kind.

The chain crosses four disciplines — Carpenter to Lv 20, Alchemist to Lv 14, Goldsmith to Lv 14 and Leatherworker to Lv 1 — so no single class can finish it unaided.

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.

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