Now, if I declare a family's IV Health = X, X will be the value for every health of every enemy. For sure indipendent for each enemy, but with the same start value and this is what I would like to avoid: the same start value for each enemy.
If you click on the family and change the health variable it will apply to all enemies in the family. But you can select the boss sprite and change it's health to 50 without affecting the other enemies.
