Initiate's Pliers

Taken all the way down to base materials, one Initiate's Pliers is 3 crafting steps deep and needs 3 intermediates — Iron Ingot ×2, Crab Oil ×1 and Iron Rivets ×1 — which resolve to 2 distinct raw materials totalling 8 units, plus 10 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 529 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 6 Fire Shard, 2 Earth Shard and 2 Water Shard.

The chain crosses two disciplines — Blacksmith to Lv 27 and Alchemist to Lv 26 — so no single class can finish it unaided.

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

Of the intermediates, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
