Dexterity

Dexterity is one of the six ability scores, a minimum natural score of 15 or 17 is required for ranger and thief dual-class combinations.
The scores adjust missile weapon THAC0, including throwing daggers, hammers and axes, it also modifies Armor Class, making a character with a high score more difficult to be hit by physical attacks.
While Dexterity has a factor in thieving skills as well, the effects are not limited to the thief class.
==Scores table==
Negative thieving skill values after the adjustments do not inflict penalties - they act as 0, but you do need to overcome them to get positive values.
