Effect: Reactive Armor protects the caster from harm by reflecting a small amount of the injury caused by bladed or blunt weapons back onto the wielder of the weapons. This spell offers no protection from magical attacks or ranged weapons. The same amount of damage reflected upon your opponent seeps through your Reactive Armor and strike you. The amount of damage absorbed by Reactive Armor is based on your Evaluate Intelligence, Meditation and Inscription skills. The higher these skills, the more damage the armor can absorb before it is exhausted. You may only have one defensive spell (Reactive Armor, Magic Reflection or Protection) active at a time.
