There should be an indestructible liquid, as well as a powder and gas. The purpose of this is that you don't have to search through the elements bar looking for an element that's the right state of matter and won't explode, destroy stuff or conduct electricity when you don't want it to.
Plus, it would be pretty easy to code. Just make the elements not react with anything.
@pilojo(View Post) BOYL releases pressure at higher temperatures. It's inconvenient sometimes... if its going to be that hot, use CO2. Too cold for CO2? use BIZG.
... what do you even need the gas for? ANAR might work better.
Of course, if you're throwing BOMBs around, none of these work.
@DRAGONF0RCE(View Post) @goten(View Post) Improvise on the elements. If some powder doesn't react with what you don't use, use that powder, for example use CLST for anything without water. The gas might be CO2 again, without water. Think outside the box, people!
