Can the Three Great Magic of Fairy Tail be only used by Fairy Tail members? Fairy Tail has three legendary magic: Fairy Law, Fairy Glitter, and Fairy Sphere.

Can anyone outside of Fairy Tail learn and use these magic?
Yes and no, some of the Fairy spells are distinctive to the guild, and the skills that can be used by outsiders are not easily learned/taught. This makes the likelihood of Fairy spells being used outside of Fairy Tail very unlikely.

As for leaving members who know one or more of the 3 great spells, there is a rule which states:


  1. You must never reveal sensitive information about Fairy Tail to others for as long as you live.


Fairy Sphere, cannot be used by outsiders

Fairy Sphere uses the Fairy Tail member mark (pair of wings mark) and the emotion of those who wield it to obtain magical power. Therefore, this spell can not be used by outsiders.

Fairy Glitter, cannot be used by outsiders

As it is a distinct spell of Fairy Tail, and the fact that it is sealed in the grave of Mavis and needs the approval of Mavis herself to use, it makes it highly unlikely that anybody outside of the guild members can/will ever be allowed to use this.

Fairy Law, most likely can be used by outsiders

It is also a distinct spell of Fairy Tail, but most likely, it can be used by outsiders.

We know for a fact that there has been at least one instance where an outsider knew how to use Fairy Law, since Laxus also knew how to use this skill. Another case is Precht, the second guild master of Fairy Tail, now known as Hades, who left the guild but could still use Fairy Law.

The likelihood of learning this skill outside of Fairy Tail is close to 0, making it not likely to ever happen.
