Going from memory, please feel free to correct me if I'm wrong:
AGI - Affects evasion and ranged combat accuracy
DEX - Affects hit rate (melee combat accuracy)
VIT - Improves defense
STR - Improves attack
MND - Improves healing ability, enhancements, and spell resistance
INT - Improves spell damage and enfeeblements
CHR - Improves song effects and lowers/raises buy/sell prices from NPC
Two points in each stat raises the corresponding ability by one point. EX: a piece of armour that provides +2 agility will increase your evasion by +1
This is how I understand it anyway, point out corrections, changes as necessary, or add stats that I forgot about.
