Uraeus Leather

Nothing in this list is craftable in turn, so one Uraeus Leather is a single step: 2 units of material drawn from 2 base items, plus 1 crystal.

That bill outweighs 3,130 of the 13,602 recipes tracked here and 389 of the 1,844 Leatherworker ones, and 9,374 recipes nest deeper.

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.

Uraeus Leather is itself consumed by 11 further recipes, spanning four of the eight crafting classes.
