I have being thinking it over and I have realised that I need to die quickly. I have no other role apart from the priest of OsiOsi but it is implied that the person who is Iffo does not know they are Iffo but will turn to Iffo at some point in the game now if I die now I can still win since my role pm is as it says above is to outlast the usurpers but if I turn to Iffo I will lose since I will soon be killed off. But all this does not matter since pisuf an old god will easily be able to out dual me with my rating of 1
