Lava

Lava is a red, glowing liquid, like oil. It uncommonly appears underground in pools, and usually kills players on touch.

Appearance
Lava is dark-red, and has a smooth, circle-like pattern in it. It glows red, and is shorter in height than other blocks. If a player begins pumping it into barrels, the lava's height lowers. Lava caves are found between 200-300 blocks below the surface.

Behavior
Lava will kill you on touch, no matter how high or low it is. However, if you buy the Lava Immunity game-pass, you'll be immune to it. If you have a Pump on-hand, you can extract lava into Empty Barrels and sell it.

Where it's found
Lava is found deep underground, usually beneath 300 depth. It's rather uncommon, rarer than Oil. A unique feature of Lava pools is that obsidian is found beside them.

How to obtain it
Like oil, lava can be pumped into barrels via pump. The obsidian that's found beside it can be mined with a pickaxe. Lava barrels are worth more than oil barrels.
