Dexterity is the primary damage dealing stat for ranged classes and jobs like archer and bard. Higher dexterity means higher attack power for archer and bard. Dexterity also increases the rate of your block and parry. The higher your dexterity is, the more likely you are to block or parry an enemy attack. Dexterity could be a valuable defensive stat for tanking classes and jobs such as marauder, gladiator, warrior and paladin.
