Yes, MoD, it does.
What the duel will do is compare your various skill points in the 'Duel type Determination' round. Your various skills in these important areas will determine which type of combat comes up.
Charisma=Vocal Debate
Dark Magic=Dark Magic Battle
Light Magic=Light Magic Battle
Neutral Magic=Neutral Magic Battle
Weapon Skill=Melee Battle
Hand to Hand Skill=Hand to Hand battle
Speed=Ranged Battle
What the game will do (and you see it doing this at the top of battles now, though it doesn't matter yet) is add up the total points between both players in all seven of these areas. Then it will take the total dark magic points (for both players) and determine what percentage that number is of the total points. That will be the percentage chance that a given contest will be one of Dark Magic. It will do the same for the other six attributes.
So, if you want to be a 'run up and hit them' type, you want lots of points in either Hand to Hand or Weapon Skill. However, if your opponant has an equal number of points in Dark Magic, then there will be an equal chance that a given bout will be one of Dark Magic.
Progress Notes:
--The game should now work for players whose usernames and profile names are different.
--Light magic and Neutral Magic bouts should now be active.
