Gliderskin Boots of Healing

Taken all the way down to base materials, one Gliderskin Boots of Healing is 2 crafting steps deep and needs 3 intermediates — Iridescent Silk Thread ×3, Green Glider Leather ×2 and Rubber ×1 — which resolve to 5 distinct raw materials totalling 16 units, plus 28 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 847 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 18 Earth Crystal, 6 Wind Crystal, 3 Lightning Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 73, Weaver to Lv 72 and Alchemist to Lv 7 — so no single class can finish it unaided.

4 of the 5 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, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
