Gravel Golem

Nothing in this list is craftable in turn, so one Gravel Golem is a single step: 3 units of material drawn from a single base item, plus 99 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 451 of the 2,216 Goldsmith ones, and 9,374 recipes nest deeper.

The single raw material is gathered, and it is time-gated: Astral Rock (21:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Nothing in the data consumes Gravel Golem: it is one of 184 end products among the 200 Goldsmith recipes at Lv 50.
