What parameters do Heroes have?

Each Hero has four Parameters: Basic Damage, Basic Health, Crit Chance, and Initiative.

The greater the Hero's Basic Damage is, the less time it takes for them to do away with their opponent.
Once the Hero's Basic Health runs out, the Hero is—yes, dead.
The Crit Chance is the chance that the Hero's Regular Attack inflicts additional Damage on the opponent.
The greater the Hero's Initiative is, the sooner the Hero acts in battle.
