Serge Hat of Casting

Taken all the way down to base materials, one Serge Hat of Casting is 4 crafting steps deep and needs 6 intermediates — Steppe Serge ×2, Grade 1 Reisui of Intelligence ×1, Marid Leather ×1 and 3 others — which resolve to 12 distinct raw materials totalling 34 units, plus 41 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,565 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 9 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 17 Lightning Crystal, 9 Water Crystal, 6 Water Shard and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 66, Alchemist to Lv 66 and Leatherworker to Lv 66 — so no single class can finish it unaided.

8 of the 12 raw materials match a gathering node, none of them timed; the other 4 come from vendors, drops or content this site does not track.

Of the intermediates, Marid Leather has the widest use: 74 recipes call for it, spanning seven of the eight crafting classes.
