Calculating Health

Health
So health, commonly simplified to hp (hit points) is the numerical representation of how much damage your character can take. Calculating this number is fairly simple and is done at the beginning of each of your level ups, so, as you would expect, you gain more health as you level up.

The Equation
So the basic equation for health is: hit die + con mod (roll that and boom, there is your health gain for the level.

First Level
As is the tradition in most games, the first level you will always have your maximum health possible.

My Rules
I do have a single rule added onto rolling health in my world. Whenever you make your roll for health, I will always roll alongside you but keep my result secret. Then, if you want, you can gamble and see if I rolled better. Be warned, if you choose mine you're stuck with it, no going back to yours if mine is worse.
