Painite

Painite is an ore in BOTH Vanilla and Modded Azure Mines. It is used in bulk (more than Dg) for mid-game upgrades. It‘s found from depths 2000m-3000m. It is a red block glowing bright red.

Tips:

It is more common at the depth of 2025m. This ore is not so tough unlike Dragonglass and Solarium, so if you’re farming this for XP you can use any pickaxe with an XP boost like Moonstone.

Trivia:

This ore in real life gets its name for being the rarest ore in earth. Many people have died trying to find this ore.
