So instead of rolling, waiting on the DM to say "Yes" you hit, then you move on, it allows you to know when you have hit or miss, and you can write it into your "Combat" narrative.
For examples of this, you can look at this ongoing combat where Ty is trying to kill us -- poor little Willow ...
Ty trying to kill PC and NGP's characters ..
Read from Ty's post halfway down ... look for CRACK!
Another thing as well which he's introduced which I'm going to steal (I checked Ty, you don't have a patent on it yet, so ... :P) is a fieldset summary at the end (and then he asked for StatBlocks as well ... it's never ending the work he makes us do)
I like the idea of the Summary, you don't have to do the StatBlocks as I will record what you have and haven't used / HP / AP's / Death Rolls / etc on the Character Thread -- see how Nice I am to you people ??
Let me know if you're happy with this ... it really does add a narrative to combat ... I can then copy over the highlights after the combat to the Narrative ... boosting the story along
