Regarding the first question, is there a way to allow the use of 4 heroes instead of 3? Is that possible?
I know how to add new heroes to the existing duel mechanic, and they will work both in duels and in trio-duels.
However, I don't know how to make it so that there are 4, 5, or 6 heroes to choose from in a trio-duel.
And I think that even if it is possible, it would likely require modifying the .exe file.
In short, I don't think this is something that's accessible to ordinary users. Perhaps some framework creators could figure it out.
