Request-Stat System Revamp

[Nightblade50]

Using VX Ace.

I am looking for a stat system that functions totally differently from the default. The user gains attribute points on leveling up, 3 or so, and assigns them to the following stats:

• Speed (SPD) – Speed defines combat order and your chance of dodging.
  
• Fortitude (FOR) – Might is one of the definers of health and defense, along with equipment.
  
• Power (POW) – Power raises attack, along with equipment.
• Charisma (CHA) – Charisma gives you discounts in shops and increases persuasion chance.
  
• Intellect (INT) – Intellect unlocks special options in dialogue, such as clever questions.

As you can see 3 of them are combat stats and 2 of them are not. I want the stats to work in this way:
Each point of SPD raises the default AGI stat by 3 and the EVA Ex-parameter by a little bit.
Each point of FOR raises Health by 20 and defense by 1.
Each point of POW raises Attack by 1.

I'm not asking for a custom script system, but if one already exists. Hopefully customizable in this way.
However, a script that works where the user gains attribute points and assigns them to the default stats would be good too, if someone knows of one.
