If you would have to hand-pump up the pressure in it with some long animation I think it could work, otherwise I don't really see how you could recharge the pressurized tank in a lore friendly way. Oh well, there is always magic, but that seems too easy :P Anyway, good idea, and something that I would like to try out if it doesn't become too overpowered :)

Second it

As the title say, I wonder if its possible to add an effect that people you kill with frost spells get the "ice form" effect on them, and people you kill with fire turn in to the "burned corpse model" (that already exists). Alternatively that they get same frost/fire/shock "paint" as the surroundings get when you blast it. Any thoughts?
