Do you want to make a slave trade a random master from a list?
If the API does not support that you could just write a CLI script that starts a random account after x time and kill the osbot season after x time. Slave has all possible masters added, hops to the world where the master is and trades its items.
Could look like something like this: Not sure how to randomise that. You would have to find out yourself. If you happen to use this methode tell me if it works out.
