New Enchantment (Soul Storm)

This enchantment would probably be a powerful and would be found on armor. When your health reaches a certain point, all souls you currently have would be released and deal damage in a circle around you, the damage dealt is proportionate to the level the enchantment is and amount of souls that were released. It would knock all mobs around you slightly back and protect you from all damage for about a second or two. There would be a cooldown on when this could happen again that would not show but would happen automatically.
