Survey Glass Block ★★★

Taken all the way down to base materials, one Survey Glass Block is 2 crafting steps deep and needs 1 intermediate — Reinforcement Supplies III ×1 — which resolves to 1 distinct raw material totalling 1 unit.

That is the lightest raw-material bill on the site, tied with 3,129 other recipes, and 4,464 recipes nest deeper.

The chain crosses two disciplines — Alchemist to Lv 100 and Carpenter to Lv 100 — so no single class can finish it unaided.

The single raw material does not appear in the gathering data, so the whole bill comes from vendors, drops or content this site does not track.

Of the intermediates, Reinforcement Supplies III has the widest use: 8 recipes call for it, spanning eight of the eight crafting classes.

Nothing in the data consumes Survey Glass Block: it is one of 175 end products among the 222 Alchemist recipes at Lv 100.
