I don't know if it was this stream that it was mentioned or another one, but I remember Larian saying (for elemental combinations) that you could use fire on water to make fog, and then electrify the fog with lightning...
My question is...why would you do that? Other than it looking different/cool, isn't it the same thing as electrifying the water in the first place?
If that is accurate, my expectation would be that while the electrified puddle acts as a stun surface, and the fireballed puddle produces fog to obscure vision, electrifying the fog would both obscure vision and create a stun field on anything moving in/through it. Essentially combining the best of both results.
I have no idea if that actually works, though.
