What is armor class? Is higher or lower good?
The greater the number the harder it is to land a damaging blow. In DDO, armor class is the result you need to get on your attack roll to hit that character in combat or that your enemy needs to roll to hit you. Armor class is determined by adding your dexterity bonus (based on your DEX score and your equipped armor) to all your various armor bonuses. You can see the exact stats that are creating your current Armor Class by hovering your mouse over the number displayed in your character sheet. One thing to remember is that there are different types of armor bonuses, and bonuses of the same type will not stack. For example, if you’re wearing Platemail, and you find a set of bracers that also increase your armor bonus, you will not get the benefits of both. Common armor bonus types include Armor, Shield, Natural Armor, and Dodge – check the details of the item to find out what it has. Armor Class can be confusing if you’ve played some D&D in the past, or other D&D games. D&D 3rd Edition
