Create a new rule called “Vital Signs” with the following text,

Each dragon has three stats, to be tracked on the GNDT. The stats are called Muscle, Scales and Heartbeat. Muscle represents how strong a dragon’s attack is, Scales represents how well a dragon defends from an attack and Heartbeat represents how much damage a dragon can take. Set all new dragon’s Muscle and Scales stats to 5 and Heartbeat stat to 100. Muscle and Scales can never fall below 1, if they would then set them to 1 instead. If the Heartbeat of a dragon falls to zero, that dragon is considered dead and its Breeder must start raising a new dragon.

I wanted to start the frame work on stats. I think this beats basic names like health lol. And while I know it talks about attacks when no rule brings up attacks I figured it never hurts to plant the seeds for battle.
