@fedorakid10 This is pretty late – hopefully you’ve solved this but here’s my solution:
Try putting the attackers into pairs, and then send the winner of that pair to battle the winner of another pair. Keep the two fighters in a pair close to each other by giving them adjacent patrol squares, and a small patrol max distance. Make sure *none* of them have ‘move to enemy behaviours’, or you won’t be able to control where they move to fight.
If the hero is going to be moving around, use buttons and tokens to mark which pair he is approaching. Then, have both partners of that pair change to the opposite alignment of the hero so that they will attack him, until he moves away again.
I’m going to test this out, but I think it will work! Hope all goes well!
