TRLL
Slowly fills up the whole screen and spells the word "Troll" after 5 mins it spawns lolz all over the screen
Sulfur and potassium nitrate.They make gunpowder if they are mixed with broken coal.
·There is one good we could ad: N2,because LN2 doesn't do anything other than cooling stuff and disappearing.
·Also, another good one could be RDWT or RADW or RWST: Radioactive wastes. It would only be destroyed by BOMB,AMTR,BHOL,VACU,SING and VOID. It would slowly kill stickman. It will appear after PLUT fusion or URAN being attacked with DEST (this could be omited or changed...). After irradiating it with neutron or hitting it with DEST, it would irradiate plasma+neutrons+heat and start slowly dissappearing.
I have textures of elements that are not on TPT that maybe you would want?
Tritium! It breaks down into deuterium and water after a while, releasing neutrons. It is much more explosive than deuterium, and if it hits absolute 0, it freezes into Tritium Ice (which multiplies it's explosive power like that of super cooled deuterium), can be produced by forcing lots of pressure on deuterium whilst slowly bathing it with neutrons
