Action	Reaction	Resistance
Body	Brawn	Agility	Toughness
Mind	Invention	Acuity	Logic
Spirit	Influence	Insight	Resolve

The above is my attempt at coming up with a simple stat/skill/ability system suitable for use in an RPG. It's a 3x3 grid with two axes. It provides a way for a character to influence, react, or resist the game world with their body, mind, and spirit. I wanted something similar to Disco Elysium's skill system, but simpler.

Example Skill Checks

• Brawn: Lift, move, or destroy objects. Melee attacks. Feats of strength
  
• Agility: Manipulate objects, ranged attacks, dodging, acrobatics
  
• Toughness: Resist fatigue, substances, damage, and the environment.
  
• Invention: Create new ideas, plans, and concepts
  
• Acuity: Think fast and recall details, recognize problems and contradictions
  
• Logic: Understand systems, assess information, rationality, predict outcomes
  
• Influence: Change minds and emotions via lies, persuasion, or insinuation
  
• Insight: Understand others' feelings, motivations, and likely reactions
  
• Resolve: Overcome adversity, resist social manipulation, willpower
  

This was basically just a thought experiment, but please let me know if you have any comments or suggestions.
