The Strength (XI)



Characters: Justine and Caroline

This Co-op is a little special— you gain ranks by entering the Velvet Room with Personas bearing specific moves. Maxing out this Co-op provides some nice Persona-related bonuses, such as the ability to train Personas to learn new skills and shed their weaknesses.

I tried my best to translate the Persona names, but if need be just refer to the Japanese names.

The first Co-op rank is gained on the 18th of May.

    I believe in rank 6→7 Rakshasa should be Lachesis.

    Good work, though! I finally got Strength to 10 today thanks to this.

      Hey man, super late but I changed it. Thanks for the info! Glad I could help!

    On 10/14, you get a mission from Mishima that, once completed, gives you the High Counter skill card as a reward, which makes fulfilling the last request very easy. With it, all you need to do is fuse Seth and give it the skill card, and you're done.
