Rule #1. In battle, the Game Master(Me) will determine how many opponents you have. Their HP and MP will be random and majority of the time they will NOT have any class.(Unless it's a Boss or something)

Rule #2. Spells - In battle, when you use a Spell or Ki-based attack, it is usually up to you how much Mana it consumes. Though, it has to be a decent amount of damage. For example, you can't use 5 mana and expect to do 50 damage. For 5 mana, the damage would be in between 1 and your base Power. The same goes for Ki.

Rule #3. Damage - damage is determined by the Game Master. It is up to him to determine how much damage you do or take from an opponent. Though, how much damage an attack does in completely how well you role play. For example, if you say "I do a lot of slashing attacks", then you'll do a single point of damage. But, if you were so say. "As a Samurai,(With 10 Strength) I jumped over to the demon, and swing my sword down upon it's head. The demon's head it slashed, and it cries out in agony."

Obviously, this is a heavy hit, and wth good roleplaying, he does 60% damage, AKA 6 points of damage. Your stats aren't the only thing that determines your well being in battle. It is a combination of well balanced stats and good roleplaying that get's good amounts of damage.

Physical attacks, such as Punches and Kickes, are determined by Strength stat. This, aswell as weapon-based attacks.

Magic and Ki-based attacks are determined by Power. Though, only for Mana users can they defend a spell with their Intelliegence stat.(Non-magic users cannot defend with Intelligence)

Finally, all long-range attacks are determined with Dexterity. Marksmen receive the bonus of having a critical hit ratio determined by the difference in their Dexterity, and the difference

Rule #4. Speed - Dodging is done with a formula and you can dodge at your own will. Basically, the Attack(M) and the Defender(P) are in battle.

M Dexterity / P Agility = Your chance of dodging.

The same thing done with Long-range attacks. For Marksmen and Dragoneir, it is a combination of both Dexterity and Strength. Whoever has the higher Agility in battle, will always strike first unless said not to.

Dodging Spells is much different and much harder. In terms of Power+Intelligence versus Agility

M Power+Intelligence / P Agility = Your chance of dodging a spell.

Dodging Ki-based attacks is just like dodging weapons attack except with Power.

M Power / P Agility = Your chance of dodging Ki attack.

Rule #5. Fainting - In battle, when your HP hits 0, you don't die but faint, you pass out. Although, for Mana-users, when they run out of MP, they too faint and cannot continue their fight. This effect does not happen to Ki-users although, when they get low on Ki(below 30%), their Strength stat begins to drop. Your Potions do not work on you when you have fainted but, you can be revived in battle from your partner's Revival Potion.

Rule #6. Dieing - The only way to die in battle, is for your body to be completely destroyed through RP and not Stat. For example, if you hit 0 HP, and your opponent decideds to go for the "killing blow", your life as that character is gone.

Health and Mana potions are going to restore a certain amount of HP and MP, while Healing and Magic potions are going to restore a certain percentage of HP and MP. They would be separated by size and quality.
In this case, for Health and Mana potions, the basic amount would be 5 points; size multipliers would be 1 for Minor, 2 for Lesser, 3 for average (no prefix), 4 for Greater and 5 for Major; quality multipliers would be 1 for Low-Grade, 2 for Poor, 3 for average (no prefix), 4 for Good, 5 for Excellent, 7 for Premium and 10 for Supreme. I think that will suffice for anyone's needs.
With Healing and Magic potions, the basic amount would be 2%, the rest is the same as with Health and Mana.
We could also have Regeneration potions that would restore a large amount (whether absolute or percentage) of health or mana over the course of time.
