Magic Drain / Gypsy Powers

Magic Drain is a part of meta-magic powers, it is extremely powerful yet extremely dangerous. Few people in history are known to have this magic ability. Even among the people that have it, it's still a mystery how it works and why every "magic drainer" or "gypsy mage" has a different way of dealing with this magic.

Human Magic Drain
The most "common" use of this magic is to drain magic powers from individuals such as mages and warlocks. It works vaguely similar to Anti-Magic, but the mage that uses it can actually absorb the magic power.

Gypsy Magic
What is known as "Gypsy Magic" is simply the advanced use of Magic Drain, not only can the user drain other people's powers, as they can absorb the magic aura from utensils, items such as swords and other weapons, even from physical features such as trees or buildings. The main difference is that gypsy magic does not necessarily drain other's mages powers, it just imitates them.

First Saga
In the First Saga, Gypsy Magic is represented through Jay Oliver, with him discovering the wonders of this magic. Although fascinating, once his magic starts evolving people around him and at high positions starts to question the safety of his powers.

New Saga
In the New Saga, Human Magic Drain is used by Nerlin, Merlin's shadow brother. Different of Jay Oliver, Nerlin can only absorb mages' powers but can't drain magic from objects or places.

Pros

 * It is one of the only "effortless" magic powers. It isn't known what is the cost of this magic, along with the fadigue. Most of the people that used this power died young or lost the power to unrelated circumstances.
 * It's versatile and almost invincible in battles and fights, as the user can drain or absorb magic from basically everything

Cons

 * There isn't a closed community that uses this magic, as few people in history used it, so the users are almost always lost and confused around it
 * As a potential destructive magic, it draws attention and many people dislike it
 * For most mages that use this magic, it has a time limitation, and probably has a limited number of drains too
