Anyways, this is a fun fan idea or whatever but one glaring issue I can find in your design is that you want Mastery to increase health. That's a little weird because Stamina already does that (making the Mastery effect redundant) and making their Mastery directly increase health is a bit weird and would likely be very, very difficult to try balancing.
