The moment Mike would hit 'accept' on the button to apply his stat boosts he would feel a rush of energy in him. He could feel his natural stamina increasing to new heights that would be only dreams for an ex in and out hospital patient. He could feel his body growing tougher and more resilient, and exponentially healthier as well as his HP would take a large leap upward thanks to both his high VIT score, but also his current level as level probably also had an affect on base HP and MP. The Physical Endurance Skill seemed to be contributing a little to his body's new-found toughness as well. 

Ren was enjoying the extra stamina he now possessed thanks to raising his VIT, which he probably wouldn't be raising for a while now as he wanted to concentrate more on Int and Wis now. The young, white haired otaku raised an eyebrow when Mike asked if he could be taught MP Armor. "Its not that simple. I learned MP Armor through a Skill I got by chance once my stats and Talents hit a certain point. It is called Mana Focus and it allows me to literally control Mana through my own natural ability and focus. Its not really something I can teach. I don't know if you can get it on your own by chance either, since we are probably going to be getting different skills based upon not only how we raise out Stats, but also how we are mentally as well. So even if I wanted to teach it, I don't think that you could learn it, and I don't really even know how to teach it in the first place".
