One of the dragon’s most powerful combat options, it can turn the tide of a battle by launching a volley of bio-lasers several times more powerful than usual, and at the same time warping the flow of energy around it to nullify enemy attacks. It takes time for a dragon to build up the energy required for this attack, and it can be used at most a few times in any given battle.
It is said, however, that the attack’s destructive power is matched only by its beauty. Perhaps the berserk attack best reveals the true nature of the dragon, as the ultimate weapon.
