Welcome to Gaia! ::

It depends, the dice version helps to prevent any god-modding but if the people are good RPers who don't god-mod then traditional is better.

I'm used to a stat based system where you trained to up the numbers of stuff like Hp, Charka control, Ninjutsu and other stats once a day and those numbers effected your battle preformence.

The outcome of a fight would be decided 45% based on your stats 50% by your rping and 5% on the dice rolls that would help decided if something hits or not.

Stam:
Nin:
Gen:
Tai:
Acc:
Mob:
Eva:
CC%:
BLC%:

Stamina: This determines how much life you're going to have in battles.
Ninjutsu: You understand and implementation of the arts of ninjutsu techniques.
Taijutsu: Your ability to focus on physical attacks on an enemy. This affects the amount of damage you can do physically as well as the use of taijutsu techniques.
Genjutsu: Your understanding and implementation of the art of illusionary tactics.
Evasion: Your ability to avoid attacks.
Accuracy: Your ability to aim, important to hit critical areas.
Mobilty: Your ability to move from point a to b.
Chakra Control: Chakra control is presented in the form of a % but you can go far above the limit of 100%, and with said 100+ chakra control a few benefits will reveal themselves to you. Some things like Kai depend heavily on chakra control and even with a low Genjutsu stat, you can cancel if your CC is high. Some Jutsu use it for damage instead of Ninjutsu or another stat as well.

Bloodline Control: Your abilty to preform bloodline jutsu

Hit Points (HP): Take your current Stam (Stamina) stat and multiply it by 10.

Stamina: 243
243x10 = 2430 HP

Chakra Pool (CP): This one is fairly simple, just like HP. Take your current CC (Chakra Control) stat and multiply by 10.

Chakra Control : 200%
200X10 = 2000 CP

I'll post more about this later
