The rulebook doesn't explain why there are counters of different sizes. Do they represent something? The size differences is not eye-friendly you really can't tell if there are 2 or 3 or even more different sizes. Even putting them together I need to focus to see if they are different sizes or not. Why there are different sizes? Do bigger ones represent 5 counters?
Also, I was thinking about "Gaining" something. When you "Gain" life it means your life buffer is increased permanently. How do you keep track of that? I am guessing maybe the bigger size cones go for the permanent-gain to indicate that your character has +1 life permanently and when you lose life counters you keep that counter on top of the character sheet to remind you that your character no longer has , say, 4 life but now he has 5 life and can heal up to 5 lives when possible and not to the original 4 life. (if I am making any sense).
So, why do we have different size counters and how do you keep track of the "gained" size of life (sense unlike strength and craft life decreases and can be healed while strength when taken it is taken and cannot be healed).
