is there any trigger to do this??? to select 2 diferent enemy heros in ech duel to fight in the center AND those heros must be at same lvl or close to make a fair battle???? plz help with this

You want the people with the highest, or just similar EXP?

For random units with similar EXP-
You could probobly do this a few ways, but I'd do something like this:

-Every .01 seconds

If
If (AbsValue((Random Unit from Team 1's EXP) - (Random unit from team 2's EXP)) is less than or equal to (whatever you want the range to be)
Then
Set these two units to variables (duelist[1] and [2]) or something)
Run the duel trigger with these 2 units
Else
Do nothing
