Divine Divinity:Character Creation

Base Statistics

Strength: adds a small amount of additional damage (Str*ClassMod, round down) to each hit, and increases carrying capacity.

Agility: affects Offense and Defense (amount dependent on class), which in turn affects how often you are hit or can hit with physical attacks. This is probably the most important stat for anyone not relying entirely on magic or poison (which can get expensive). Base weapon damage completely trumps strength, and a few extra points of offense makes a much larger difference than increased damage. A few extra points of defense can increase survivability more than increased Vitality as well.
