As one who supports a good detailed fight scene, there is a fine line giving the blow by blow.
Just remember the old saying: Show don’t tell.
Took me years to fully comprehend it and apply it successfully. It’s great to tell the reader what is going on in a duel, but it’s better to tell with the show, if you understand my meaning. Find a way to present your battle details without droning on about parries and reposts and blade flips. I was a fencer, so I understand the pull to do it.
