Painite

Painite is a pretty common ore if you're in the right depth. It can be found normally pretty easily and it can also be dropped from Zentients. Painite is a very useful ore since it is used in Mining Ops, Data and Analysis, and Research and Development upgrades. It can also make the Painite Pickaxe, Newtonium Pickaxe, and Yuntonium Pickaxe. Painite is just overall a very good ore and you probably want to grab it whenever you see it.
