Action Combat by Proski is one of the best mods for combat on the nexus, and personally, is my favorite. He has said that he will no longer support development of Action Combat however, due to a lack of initiative to do so. I would occasionally get crashes from using action combat, but the parrying effect worked wonders and it was hard for me to give it up, but I had to because I couldnt use Action Combat with my mods. Well, I finally learned how to mod and how to read papyrus script and I trimmed out all of the other effects and code that didn't pertain to the weapon parry effect for personal use I thought I could upload it to the nexus with Proski's permission.
