v1
Stamina represents your character ability to dodge, evade or otherwise avoid getting injured. The amount of Stamina you have is determined by your class and Dexterity modifier and you gain more as you level up. Stamina takes up a portion of your Maximum Health which combines your Hit Points and Stamina together. When your stamina is reduced to 0, you gain the Bloodied condition and start reducing your Hit Points. Any excess damage from your stamina being reduced to 0 is carried over to your Hit Points.
For example, if you had 5 stamina left, and 15 Hit Points and took 10 damage, you’re stamina is reduced to 0, you gain the Bloodied condition and now you have 10 Hit Points.

Some way to spend stamina to perform additional actions in combat. When you’re hit, you can choose to lose stamina or Hit Points. You can only lose stamina if you choose to have damage go there instead. Bloodied would have to mean half health again
