Do you mean choosing as in the path it takes through the air to get to the target, or actually choosing to make the lightning bolt strike your enemy? Diablo isn't completely realistic, but whats not to say to counter the latter that the wizard's lightning spell is actually a form of electric repulsion/attraction that disrupts the electron flow on/around the enemy? This would make for a lightning bolt that isn't random.Quote fromChoosing where your lightning go is a no to me, since thats what lightning is about: randomness.
And if we go the logical way, if the color depends on how hot the lightning is, then we could assume that when you are more powerful, its hotter, and so the color would change accordingly.
So the lightning would always be white, but the outline would be purple first, then as you gain level it gets more blue, then green, then yellow.. orange.. and end up red.
...they should just include customizable lightning color ^.^
You seem to have to it backwards. The blues/purples would be the hottest and oranges/reds the coldest.
I like this idea though except not to go overboard with it, the colour would be a soft tinge while the bolt will basically be white.
