Armor

Armor is something that everyone has to have. It's the easiest and best way to reduce damage inflicted from hits and spells in combat. There are 4 different types of armor, Pierce, Slash, Bash and Exotic, they each apply to the type of damage dealt from weapons and spells. Spells, all minus the telekinetic punch/bash/slash/pierce spells will work against your exotic rating. Any weapon that doesn't fit into the slash/bash/pierce sections will also go into exotic.

Armor works on a base damage of 100%, meaning each hit to you will cycle through your armor and decrease by the amount you have in that section on the part of your body hit. For example, if you're hit by someone or thing that does 100 damage and they hit your leg, it will first go through the leg filter, which reduces it to 50%, then through your armor, which if it was at 50 would reduce it to 50% again, to 25 damage. On top of that, there are spells like Sanctuary and Protection from Evil which will reduce the damage further.

Armor can also be gained through the use of spells, which is probably the best way to reach the max of 75armor in all areas. Below is a list of all the armor spells that can be cast and approximately how much they give at archon level. (The armor given will be lower, depending on your current class.)
