Would be interesting to have parries able to inflict posture damage/reflect it back onto the enemy when it occurs if War Dance is installed.

War Dance is a combat gameplay overhaul kinda mod with skills and such.

The author also has a thing called attributizer that lets you put attribute based stats onto things too. Like the shields having reduced attack rate so they can't be attacked with over and over (since they deal decent posture damage in war dance making them kinda strong for stunning things)
