Bathroom Floor Tiles

Taken all the way down to base materials, one Bathroom Floor Tiles is 3 crafting steps deep and needs 5 intermediates — Cut Stone ×5, Varnish ×3, Steel Plate ×1 and 2 others — which resolve to 7 distinct raw materials totalling 46 units, plus 56 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,508 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 29 Water Shard, 15 Wind Shard, 5 Lightning Shard and 2 other kinds.

The chain crosses four disciplines — Alchemist to Lv 43, Goldsmith to Lv 30, Armorer to Lv 27 and Blacksmith to Lv 26 — so no single class can finish it unaided.

6 of the 7 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
