|Second Origin Activation|
Second Origin Activation (二原解放, Nigen Kaihō) is a spell exclusively mastered by those mages who possess the control and power to summon their Second Origin without it passively inducing its effects. It was first shown by Erza Scarlet, though other mages had commenced the practice as well.
The rumored Second Origin (二原, Nigen) is, in fact, wrongly named. When considering the nature of the Magic Origin (魔原, Magen), the Second Origin and its activation is simply unlocking the full extent of one's Magic Origin and power. There are a number of ways one can go about unlocking it: it can be a natural process that takes a considerable number of ways, a sudden surge of willpower during a situation of crisis or accelerating the process through magic such as the Arc of Time. However, all of these cause the passive effects of unlocking one's Second Origin to be visible. In the case of Dragon Slayers, it appears to dramatically improve one's physical prowess, but also the intensity of their magical power. However, in the case of standard mages, it vastly increases the quantity of magic they may use in any given situation for a brief period of time, giving them access to magic and equipment that can potentially rewrite the laws of magic itself, though the claim itself is debatable.
In order to unlock one's Second Origin without inducing its passive effects all the time, one must firstly impose a sealing condition onto the said portion of the Magic Origin. Due to magical energy being so closely aligned with one's willpower and conviction, this is done so through a rather unique method: the Pact (盟約, Meiyaku). The Pact, in this case, is one that the user makes upon reaching the full level of potential within one's Magic Origin, which in itself takes a considerable amount of time, or emotional upheaval, to achieve. When doing so, the Pact automatically causes this portion of one's magical power to be sealed in a series of magical seals that can only be unlocked with the fulfillment of the Pact; in the case of Erza Scarlet, it appeared to be when the life of herself and her friends were in mortal danger, which enabled her to wield the fabled Nakagami Armor. However, due to the strain of the sudden outpour of magical energy within the body, this state causes one to be heavily drained following its immediate use, despite causing a notable increase in the capacity of one's magical power.
However, considering that the sudden outburst of magical power within one's body is caused due to the extreme sealing caused by the Pact, one is since unable to recreate the same seal due to the strictness of the requirements. As a result, the portion of magical power sealed is then assimilated to the natural reservoir of magical energy they can access within themselves. While this causes a considerable increase in their base capabilities, given that they can induce the passive effects of the Second Origin "state", they are since incapable of such a large outburst of magical energy through natural means.
