Agent0fN0thing: Attorney at Rules Law here, to provide some advice on how critical damage works in 4th Edition D&D. When you roll a 20, your damage die is maximized instead of multiplied. Since many basic attacks already include multiple damage die (such as 4d6+6, for instance), this can add up quite swiftly. Once you have equipped a magic weapon or implement, critical damage goes up even further by adding an additional bonus damage die that is rolled on top of the maximized normal damage. These are multiplied per enhancement bonus, and is usually, but not always, a d6. See the relevant weapon description for details on critical dice. Some weapons, such as the greataxe, possess the "high crit" quality, which adds a further damage die based on the weapon's damage. In the greataxe example, a basic greataxe would roll an extra d12 in addition to the maximized weapon damage. A magical greataxe would get that, plus the extra critical dice based on the enhancement bonus.
