I'm kind of stuck here. I was planning on doing a simple Strength/Agility/Intelligence stat deal, with Strength increasing Max HP by 1 for every point in it, Intelligence doing the same as Strength but MP instead of HP, and Agility...Uh, yeah.
I scrapped that whole idea. How should stats work? Any grand ideas, guys? Thanks! Also: I'm using a 1d8 the core of my rolls, so...Yeah.
Aha! This shit is in my bowl now.
Stats are a way of measuring three aspects of a character, at its most basic it can simply be broken down into Physical, Mental, and Social. Each of those however can (and often will be) broken down further into more familiar sounding attributes.
Physical
>Can be broken into Strength, Endurance, Agility, Stamina, Speed, Reflexes, Vigor... (ad infinitum)
Mental
>Can be broken into Intelligence, Willpower, Mind, Wits, Arcane, Wisdom, Vim... (ad infinitum)
Social
>Can be broken into Charisma, Heart, Soul, Courage, Beauty, Guile, Tact, Verve... (ad inifitum)
A three-fold stat system is simple to use but it is essential that one pick carefully, in this case I believe the problem is that you have two physical type stats and only one mental. You can alleviate your problem most easily by adding a single mental stat to balance it out into four, or change the agility stat to a social one.
Example: Add a Will stat to your Strength/Agility/Intelligence. Str gives MaxHP +1, Agility decreases your chance to be hit by X (a 1/6th system can work quite well), Int gives MaxMP +1, Will decreases magic damage/effect by X.
Example 2: Change agility to Heart, Str and Int function as before, Heart gives +X defense to both Physical and Magical OR it gives .5 to both MP and HP.
