The meaning of “intelligence”

"Charisma, piety and intelligence are modifiers for melee/spell damage in combat for different character classes". Only computer gamers can find a sense in the line.

Just to remind you :
Intelligence: Ability to learn or to understand, to deal with new or trying situations
Charisma: Personal magic of leadership arousing popular loyalty for a public figure
Piety: Dutifulness in religion

Something should be changed here. God doesn't like games that wander too far from reality.
or rather from mainstream reality :)~~
