Reign of Kings Points forces players to value their life

Hello, I have this idea to make something like "strength points". This would be a percentage of points that a player would have to collect quite a long time, for example, about a day. Lets say that 100% of the points would give player 40% more power / damage. Players would value their life on more than just Items that they have. For example taking to jail/cage some opponents and taking ransom for them would make sense
