Post mark of the fool 9 Alex

I know 10 is out already and it’s likely the last book of the series but I’m an audiobook listener. I’m wondering what he’s capable of now. How much help does the generals mark give him? I know he went through route of life enforcement through a new application of blood magic so would regular life enforcement even work on him anymore? If so and if he has an affinity for it would the general help him progress through it? Yes already an arch wizard and getting better at fighting but life enforcement is some ring that would majorly benefit his survivability
