As stated in this thread, there has been controversy about the extra skills of 7* units, Kurt and Claire.

This is directly off of JPBF's news and is 0% my opinion.

First of all, no laws were broken as Alim had originally made the skills available by using friends with either of the corresponding units as their leader.

Second, Alim had been receiving many complaints on the matter, still, so they "made a modification" to the ES requirements. This is an appeasement so that players will not have the image of Alim as a "shady company".

• After the next version update, Kurt or Claire's ES can be activated either by having the other unit in the party (friends do count) or when they have a certain sphere equipped.

I do not know what sphere(s) are specified or how to get them, but they will most likely be retrievable by F2P players.

The extra skills will not activate twice by using both methods.
