How do I create Dynamic Lightning?

This is the current road block I'm at.

I'm planning on making a RPG with magic and the like, fire balls, ice shards, lightning bolts.

I'd really like to know how to create dynamic lightning.

I think there's a lot of issues before spending time on lights effects

But if you want to get some information, google "normal map construct 2" and you'll find what you're looking for.

I'm trying to figure out how to make LIGHTNING not LIGHTING..

Got any clues where I can look for it?

Oooooooooooooooooooh sorry for that

I have no idea sorry :s
