Fight scenes can be difficult to write. After all, there is a lot going on and putting that kind of action down with words rather than visuals can be tough. Some novels I've read had painful fight scenes that I either skipped completely or re-read just to figure out who was doing what. So this tutorial is an amalgamation of my thoughts on the best ways to do it.
Characters are the life breath of your novel so you need to create strong, realistic, memorable characters. You want your readers to connect with them, to cheer for them, to grieve with them...to do that, you need to make realistic, memorable characters.
