Pure Massacre

In my life as a DM I sometimes struggle to get my players to tell the story of battle. they love the clink clink of the dice. But focus on that and the math more than the story of slicing and dicing and flips. 

Using a set of dice as the enemy, players get rewarded when they describe the battle, seek out the weaknesses and put together great sequences. 

Still testing it. Would love some feedback. Does this actually work, or are there rulesets out there already that do this better.
