When your Stamina reaches 0, you become exhausted.
Overexert: Each additional Stamina Point you spend while Exhausted increases its level/stack, compounding its negative effects. You receive all negative effects of your current plus previous stack effects.
At 1 stack, your Speed is halved.
At 2 stacks, you have disadvantage on all Skill Checks.
At 3 stacks, you have disadvantage on Attack rolls, and your Speed is halved again.
At 4 stacks, you’re Passed Out until you’re no longer exhausted.
At 5 stacks, you die.
While Exhausted, resting removes stacks of Exhaustion instead of restoring your Stamina, every 2 hours of Rest removes 1 stack. When the last stack is removed, your Stamina is restored to 1, and you can regain Stamina through normal Resting again.
