Void Out Bomb

The Void out bomb (VOB) is deadly device that condenses the void partial inside those who fail to become witches. Their bodies soak up the partials and become infested but instead of turning into Grimms due to the casing of the bomb being similar to the Witch armor with the same metal and symbol. With one slight change negative energy would also be poured in mixing with the magic allowing for a completes change in how the reaction will release. The partials will instead of eating all magic they will eat all life force within the blast range. Magic pours into the bomb allowing the Void partials to compound on each other creating a deadly chain reaction. When the case is opened or destroyed by outside forces the bomb detonates releasing the Void partials in all direction. All life within the Blast range is eaten alive.
