Proprius is latin for peculiar.
With a colour code of: HEX(#eaecef) / rgb(234, 236, 239) and abbreviation of (PRPR)
Proprius is a wall that creates a vacuum chamber when completely enclosed. If it is not closed, it repels everything five pixels before they can contact it. Once enclosed, the chamber allows all particles to fall at the exact same rate. It also sets the base temperature and pressure of all materials to zero. No fire can be lit when the wall is closed. I.e., a hollow square or rectangle. No explosion can happen. Water immediately begins to freeze. When powders hit the ground, the particles spread out evenly. Light can be used in the vacuum. No gravity works when the chamber is closed. Means cities created with only powder will topple and the particles will even out on the ground. Means no bomb will have a chance of working. Means no electronics will work. All liquids, metals, forces, explosives, powders, gases, and radioactive elements weight, fall, and move at the same speed. Means pressure bombs do nothing. Lightning also can’t be used.
If life is placed in the vacuum, it will immediately fail. Same applies to a stickman and fighter. They all die.
Actually, it does both, it boils, but the boiling slowly cools it until it freezes, you can do this with other liquids such as nitrogen and mercury, or anything really, except helium, helium doesn't freeze.
no, a pure vacuum will never make something freeze. As for helium not freezing: Everything freezes if cold enough.
As I'm sure you're aware, TPT is anything BUT a real physics simulator. If you wish to make a suggestion for something, it mustn't follow all reality. You need something with a bit of umph and fantasy. As I'm sure you're aware, the gravel in reality doesn't change colour based on velocity, we don't have simple particles called 'bomb' and 'destroy', 'thunder' isn't a plasma like liquid, so why shouldn't water freeze in a TPT vacuum?
