[@Flynn] (Not quite sure how whale oil would make a gun function, since I've never played Dishonored. Is this as a propellant that actually ignites and sends the bullet flying or something, because that'd make sense I suppose.) But basically with guns it's less of a standard use weapon and more of an unusually powerful ranged weapon for when something with less punch won't suffice? I also assume this would make javelins, crossbows, etc the primary means of killing things without getting into their faces, which I admit is my preference. 

I'll start working though with the assumptions above, if they're wrong just boop and I'll change things.
