Level Up Strategies
Generally sprinting four times to total depletion of the Stamina bar will increase your Cardio skill from 1 to 2. Every level after that will require approximately one more sprint per level up.
One strategy for leveling up quickly is simply to sprint where-ever you go with whatever character you are using. This can be risky as sprinting especially at low levels will quickly deplete stamina and leave you vulnerable to attacks by Zombies. Of special concern are Ferals and Juggernauts as they can quickly kill a character if they are stumbled upon at the wrong moment.
Another strategy is to simply have characters 'sprint the yard.' Most home bases will have a large area outside that is still within the secure perimeter of the base but also will cause stamina depletion when running. Running inside this area will increase Cardio as well.
It takes approximately 39 full sprints from maximum Stamina to 'nothing left' to improve a character from Level 1 Cardio to Level 7.
Traits that Affect Cardio
Traits that improve the rate at which Cardio is gained generally reduce the number of sprints required to improve Cardio by 1. Conversely traits that lower the rate at which Cardio is improved will increase the number by 1 usually.
Traits that Improve Cardio Gain
Traits that Decrease Cardio Gain
- Asthma Attacks: Improves cardio slowly (Approximately half normal Cardio gain).
Traits that Offer Additional Ranks of Cardio
- Liked to Hunt: +1 rank to Shooting, Cardio and Wits
