The most feared of all elementals, the Elemental of Void is a swirling hole of anti-energy and anti-majik. Void Elementals are very difficult to summon, and thus are thankfully rare, as they said to be even more difficult to banish.
The touch of a Void Elemental drains experience levels; knowledge and power sluicing away from opponents like butter before a roaring flame. It does not leech this energy, like undead do, it annihilates it. Levels lost to a Void Elemental cannot be recovered majikally, they can only be replaced by normal advancement.
