Critical Hit
When a critical hit is scored, you achieve maximum possible damage from the attack in addition to rolling the weapon's dice and adding the damage. For example, if a weapon deals 1d4 damage, and you have a +2 bonus from dexterity, that weapon deals 6 damage from the +2 plus a 4 on the 1d4, and then you add an additional 1d4 damage, so damage would range from 7-10.
