Void Powder has ONE use and that is for mid map cannons. Why not expand on it? Allow any cannon to use void powder doing 90 damage total instead of the 50 like normal powder. This will increase the demand/farming of mid map mobs. Make the smoke red so it is noticeable if someone is blasting void powder. Void powder could be something more. You have to farm it cannot craft it so why not make it best powder for ANY cannon. Kinda like fine arrows I guess.
