also im tired of oil being the expensive thing with all the hype, we have more elements than just oil.
deuterium is weak in it's natural form, it requires expenisive super cooling machines or irradiating ELEC reactors to purify and condense to nuclear bomb material, EXOT is also great as it can be easily be made into a time bomb, also it dosent need expensive machines to purify it.
btw deuterium oxide irl is commonly found with high amounts of tritium so a more realistic gas would be hygn, and as it is canon in tpt's lore and stuff(idrk) deut would be a nuclear bomb ingredient and therefore expensive (idk about any of this)
yeah, exot better also i feel like deuterium would emit a gas so i made it noble, also i feel like EXOT is a combo of DEUT, a medium (water), QRTZ, Radioactive stuff, and maybe other stuff (EXOT more expensive than noble and deut btw)
u got deuterium and noble right over there!
