<Snipped quote by VKAllen>

Haven't decided on a definite number yet as I want players to be able to change it, yet I don't want it tied to a stat that can be heavily favoured.

For now I will just say 10 and see how that works under varied conditions.

Perhaps we could use FF Dissidia's system. Fighters would accumulate and trade bravery. upon activating an Ability, it deals lethal damage and that health is 100. Person who drops to 0 loses.
