These were Kaiden's current stats. He was a completely average man before he started his manic training regimen with Liam, so he was likely 10 in all stats a month ago. He couldn't tell for certain, though, because as a non-awakened, he had no access to his stat window.
The changes the mana apocalypse introduced into the world were quite game-like, but one thing was vastly different from video games—people didn't have HP bars. You died when you were killed, not when a magical HP number reached zero.
Vitality was paramount in making one more durable. It provided a flat resistance against all that was hostile. This stat made one's skin more durable, strengthened their bones, gave them more poison resistance the more Vitality they had, etc. To summarize, the higher one's Vitality was, the harder they were to kill.
