Use Morgana if you can. Smack it around for a bit until it’s Morgana’s turn. Once it’s his turn, smash it with Magarudyne to put them down.

Boss Fight – Treasure of Mementos?

This particular boss fight is scripted. You won’t have much problems so I don’t suggest expelling any SP. All you have to do is sustain through the battle. The main point is to learn about the item’s nature so keep on attacking until you reach the cut-scenes. I suggest though that before you head down here that you’ve saved. It’s gonna be a loooong cut-scene.

Velvet Room

Boss Fight: Justine and Caroline

Again, this isn’t really a boss fight. All you have to do is let the battle roll on until the true enemy reveals itself. After that, refuse the enemy’s offer before finally gaining control over your character.

You can go back to the beginning, outside the velvet room, and have Caroline completely restore your health and sp.


you are pretty fucked if you haven’t been saving up master coffee and curry for this mission. Its impossible to do it without


I had no idea what what was about to hit me going down there. This dungeon is probably as long as the damn Shido Ship and you have to do it in a single day.

Guide was awesome, thank you so much for the hard work you put in!


I’m still learning from you, but I’m making my way to the top as well. I absolutely love reading everything that is written on your blog.Keep the stories coming. I liked it!

Great guide, the only thing I would fix in the future is hide information that naturally develops the story. (Justine and Caroline) Hold back that type info since it’s part of the story. Like say, there’s a boss battle but nothing can be done, mention it, but not who or what’s in it. That way it keeps the story hidden. Since it’s not an actual battle that needs a guide.


Thx for the guide


Plz make better guides


What else could you possibly need for a straightforward dungeon like this?
