1 of Extinction's 4 caves have no published entrance coordinate — they have guides and are in the list below, they just cannot be plotted yet.
A crate draws one or more item sets, and each set then picks a few entries from its list. The per crate figure on a row folds those rolls together: the chance of finding that entry in a single crate. Quality tiers run Primitive → Ascendant; "blueprint" means it drops as the blueprint, not the item.
