I just noticed that even though irregulars can break all the rules of towers including the rule that grants zahad and ten family leaders their immortality, they must follow one absolute rule that they must pass a test in order to go up the next floor.

Or simply irregulars can break all the kind of not the original rules of tower, like the immortality of zahad, and the rules made my ten family leaders. Although they rule the current but they are not it's rulers in true sense since they failed to reach the top.
