Berserk Magic is a forbidden form of Take Over Magic, considered lost and forgotten but was researched and futher developed by Darkman.

Description
Berserk Magic is a special form of Take Over that transforms its user into a feral monstrosity that has regard for only one thing, battle. The user's will and personality no matter which, will transform to that of a violent, aggressive and unstable monster who will attack anything that sees as foe, and not even allies are completelly safe from this rampage. This form however brings a massive increment in both the physical and magical abilities of its user.

Origin & History
This form was once used by many Take Over mages who sought a great power. However this proved too much for them, that they finally ended attacking friends, and family like foes, history records show that even the most powerful Take Over mages in history have been consumed by this magic's power, as such no one ever attempted to use this spell anymore and how to transform was eventually forgotten. The Dark Mage Mastermind Darkman however, did a large research to test the magic and was the first to ever be successful in using it while maintaining his sanity, albeit with difficulty, by willingly use the darkness of his heart as a vessel to successfully manipulate the magic's power.

Spells

 * Saevam Impetus (Barrage Onslaught): A spell in which the user throws several powerful fireballs at the opponent in rapid succession. The aggresivity of this spell is such that not even Natsu is capable of eating all the fireballs, before being injured in the process.
 * Collisus Genocidium (Genocide Impact): The user pummels the ground with fury successive times with such strength that it unleashes shockwaves that crush the earth as they travel. The area of effect this multitude of shockwaves cover, makes it very difficult for somebody to avoid them in the ground.
 * Concito Dissulto (Bursting Rush): The user surrounds himself in magical power and leaps at great speed and force. So much that it can break through Gray's Ice Make: Wall with ease and deliver a brutal blow to him.
 * Lux Fulminus (Fulminating Light): The user traps the foe in a magnetic field then pummels him with blazing fists. The unfortunate victim is sent flying engulfed in a explosion.
 * Violentia Indomitus (Uncontrollable Violence): A powerful surge of hatred that surrounds the user in a black aura, augmenting his already monstrous power to destructive proportion, although no other spell is seen used in this form, the boost is so great that the punches and kicks are set ablaze, the power granted being so intense that not even Erza's Purgatory and Fire Empress Armor were capable of sustaining the beating for too long.
