Example:
In this example you'll see that after you hit the attack button a "notice" pops up below the person you attacked. It shows your current HP, turns left, money/blood gained, and (I forgot to add to it) how many souls you acquired. It will also allow you to view the battle report (what we normally see now).
Here is an example of losing:
You'll see that you're now dead, how much money you lost, and the quick heal option.
I believe this system would allow players to easily fight others with less fuss. For people with slower computers they no longer have to load a page then go back then load another one over and over to fight. Just attack, wait the 3 seconds, attack, etc. Streamlined.
